INTRODUCTION Welcome to the exciting world of GPS! Whether youre a first-time user or a professional navigator, youll find the GlobalNav 200 is a full-featured GPS receiver at a price that was impossible just a few years ago. The Rockwell receiver built inside has 12 channels that will track all of the satellites that are in view of your location. Its acquisition time and tracking ability are second to none in its class. The Global Positioning System (GPS) was developed by the United States Department of Defense as a 24-hour a day, 365 days a year global navigation system for the military. Civilian availability was added with less accuracy using the same satellites. Twenty-four satellites orbit the Earth. Three of these satellites are spares, unused until needed. The rest virtually guarantee that at least four satellites are in view of anyplace on Earth at all times. The system requires three satellites in order to determine a position. This is called a 2D fix. It takes four satellites to determine both position and elevation, (your height above sea level - also called altitude.) called a 3D fix. Remember, the unit must have a clear view of the satellites in order to receiver their signals. Unlike radio or television, GPS works at very high frequencies. The signals can be blocked easily by trees, buildings, even your body. Fortunately, they do travel through glass and plastic, so your receiver will work in the car, if it has a clear view of the satellites through the windshield or side windows. Let someone else drive if you use it in a car or other vehicle. Never use this GPS receiver while operating a vehicle! The first time you use this unit, walk outside and turn it on in your backyard, an open field or park. Once it locks onto the satellites, you can experiment with it around buildings and trees. This will give you some idea of its sensitivity to blockage. Like most GPS receivers, this unit doesnt have a compass or any other navigation aid built inside. It relies solely on the signals from the satellites to calculate a position. Speed, direction of travel, and distance are all calculated from position information. Therefore, in order for it to determine direction of travel, you must be moving and the faster, the better. This is not to say that it wont work at walking speeds - it will. There will simply be more wandering of the data shown on the display.

S/A - What is it? Another factor that greatly influences the receivers ability to determine position is SA. The United States government intentionally degrades the satellites signal for civilian users. They introduce small errors into the satellites signals that makes the GPS receiver less accurate. These errors are called selective availability, or SA. How bad is it? They guarantee that the position reported by a GPS receiver that meets their specifications is within 100 meters horizontally and 150 meters vertically 95% of the time. (The position can be better than that or worse than that the other 5% of the time.) In other words, the position shown on your receiver is within 100 meters of your actual position, 95% of the time. Thats over 300 feet! Not exactly pinpoint accuracy, but then few people need positioning accuracy greater than this. However, if you do want better performance, (and who doesnt?) many manufacturers (including Lowrance) sell a DGPS receiver that attaches to your GPS receiver. The DGPS system transmits correction signals that nullify the effects of SA. The DGPS receiver takes signals from these land-based transmitters and gives them to the GPS receiver which then uses them to show a more accurate position. The ironic part is the federal government implemented SA and is also operating many DGPS transmitters. (You can use the signals from all of the Coast Guard DGPS stations for free, by the way.) The downside to this is it requires another piece of electronic gear (the DGPS receiver) which usually isnt small enough to carry with you, but will work nicely on a vehicle. And you have to be close enough to a station to receive the DGPS signals. Dont Get Lost Generally, you find that using your GPS receiver without DGPS is both easy and amazingly accurate. Its easily the most accurate method of electronic navigation available to the general public today. Remember, however that this receiver is only a tool. Always have another method of navigation available, such as a chart or map and a compass. Its a good idea to carry spare batteries with you, especially if youre venturing into unknown territory. Also remember that this unit will always show navigation information in the shortest line from your present position to a waypoint, regardless of terrain! It only calculates position, it cant know whats between you and your camp, for example. Its up to you to safely navigate around obstacles, no matter how youre using this product.

KEYBOARD The keyboard has twelve keys. The arrow keys are tied to most of the features, letting you easily move the plotters cursor, navigate through the menus, make selections from menus, and other tasks. The WPT key lets you create, save, and recall waypoints and routes. The PAGES key switches the unit between the three major displays: windows, navigation, and plotter. To select different features, or to modify functions, press the MENU key. The Z-IN and Z-OUT keys zoom-in and zoom-out your view on the plotter screen. The ENT and EXIT keys let you enter or erase selecWPT PAGES tions. The PWR key turns both the GlobalNav 200 and its lights on and off. Note: To prevent an accidental power shutdown, you must hold the PWR key down for a few seconds in order to turn the unit off.

OPERATION

Turning Power On To turn the GlobalNav 200 on, simply press the PWR key. A screen similar to the one at right appears. Read the message on the screen, then press the EXIT key to erase it. The GlobalNav 200 is now ready for use.
MENUS Most of the GlobalNav 200s adjustments and features are found on menus. Pressing the MENU key lets you view the menus. Different menu items are added to the basic list, depending on which page (plotter, navigation, or windows) the unit is on. This gives you the features that are specific to the page you are on, but also has items that are used on all pages. Pressing the up or down arrow keys moves the black box to highlight different menus on the list. Pressing the right arrow key selects the highlighted menu item. To erase a menu, press the EXIT key.

Finding Your Position

Cold Start When the GlobalNav 200 is turned on for the very first time, it doesnt know where it is, nor what the local time or date is. If you tell it your position, time, and date, the unit should take less time to lock-on to the satellites and give you a fix or position. However, if you dont want to push buttons at this time, thats fine. The GlobalNav 200 will lock onto the satellites and give you a position without any input from you. This is called a cold-start. It simply means that the unit is searching without help for the satellites that are in orbit. A cold-start can take over two minutes to acquire enough satellite data to determine your position, although it typically takes less time than that. To use your GlobalNav 200, first make certain you have a clear view of the sky, free from any obstructions such as trees or buildings. Also, dont
try to use it under a carport, covered boat dock, or inside a building. Turn the power on, press the EXIT key to erase the opening message and watch the display. As you wait for the GlobalNav 200 to find your position, youll see numbers flashing on the display. Anytime you see flashing numbers, it means the GlobalNav 200 does not have a position! Do not rely on any data that is flashing! Once the GlobalNav 200 locks on to the satellites and finds your position, it shows a Position Acquired message on the screen. It also stores the satellite data in its memory. The next time you use the unit, it should take much less time to lock on. Thats all you have to do to find your position. Your local time display may not be correct when the cold start method is used. See the initialization section for details on changing the time.

REPROGRAM WINDOW GROUPS You can customize the window groups to meet your own needs. The GlobalNav 200 gives you 35 different windows that can be rearranged into many combinations. To reprogram a group, first go to the pages menu and select the group that you wish to change. In this example, were reprogramming group A, shown at right.
Next, press the MENU key, highlight the "Reprogram Groups" label and press the right arrow key. A screen similar to the one shown at right appears. The altitude window appears at the top of the screen. To view a different window, press the left or right arrow key. When the desired window appears, press the down arrow key to select it. In this example, we selected the digital clock. The GlobalNav 200 will add this window to the selected group. It then shows the selected windows position, as shown at right. If you want to delete this window from the group, simply press the up arrow key. The next window selected was the voltmeter.
Continue selecting windows in this manner until all of the desired windows have been added to the group.
When the last window has been added, the GlobalNav 200 returns to normal operation with your reprogrammed group showing on the screen, as shown at right.
RESET GROUPS To restore all windows groups to their factory settings, first press the MENU key, then highlight the System Setup label and press the right arrow key. Now highlight the Reset Groups label on this menu. Press the right arrow key. A message appears, asking if you really want to do this. Press the right arrow key to continue, or the left arrow key to exit without resetting the groups.
press the EXIT key to erase the pages menu. Satellite Information Screen (Group O) This screen shows technical information about the status of the GPS receiver. The receiver has twelve channels. Data for each channel is shown as bar graphs on the right side of the display. Every satellite in the constellation has a number assigned to it, called the PRN. The bar graph is beside each satellites number. The higher the bar on the graph, the better the signal is being received from the satellite. Each satellite is also shown on the circular graph at the top of the screen. This shows you not only which satellites are in your area, but also their direction from your position, and their elevation (distance above the horizon.) The small inner circle represents 45 above the horizon and the large outer circle represents the horizon. A satellite is straight above you when it is at the intersection of the horizontal and vertical lines that pass through the circles. The N on the left center of the screen shows the direction of north relative to the satellite graph. The FIX number in the top left of the screen shows the quality of fix. If the FIX is 9, then it's the best you can get. A FIX of 1 is the worst. The light bulb in the top right corner of the screen shows when the backlight is on. CLOCK Whenever a clock, timer, or alarm is showing on a display, new items appear in the list when you press the MENU key. These items let you set the clocks time, alarms, or the timers. Set Local Time If the time shown on the clock display is not your local time, change it using the Set Local Time function. To do this, press the MENU key, then highlight the Set Clock label. Press the right arrow key. The screen at right appears. Using the right and left arrow keys, move the black box to the first number in the time that you want to change. Now press the up or down arrow keys until the desired number shows. Continue until the time shown in the display is correct, then press the ENT key. This enters the new time and erases

which means its ready for change. If you dont want to change this box, simply press the up or down arrow key to move to the box that you do want to change. In this example, we will change the BRG box to altitude (ALT). To do this, simply press the left or right arrow key while the box is flashing. The box changes each time the arrow key is pressed. When the desired box appears, then you can change another box or save your changes by pressing the ENT key. If you want to leave this screen without saving the changes, simply press the EXIT key. In this example, we simply changed the BRG to ALT, then pressed the ENT key. The screen on the right on the previous page is the final version. Use this same method to change the NAV screens. WAYPOINTS The GlobalNav 200 gives you the capability of creating your own database of locations, called waypoints. You can save your present position, cursor position, or enter a latitude/longitude and save it as a waypoint. The GlobalNav 200 can store up to 999 waypoints. Saving Your Present Position as a Waypoint (Quick Save Method) To save your present position, simply press the WPT key twice. The GlobalNav 200 puts your current position into the first available waypoint number on the list. A message appears on the display telling you the waypoint number it just used. This also momentarily places you in the database menu. Anytime a database menu is showing, simply press the WPT key once and the unit will store your present position in the waypoint list. Every time you save a waypoint, the date and time are logged along with the position data. Its position is also placed on the plotter as shown above. In this case, waypoint number one was assigned when we quick-saved our position. Saving The Cursor Position as a Waypoint When the cursor is showing on the plotter and you press the WPT key twice, the GlobalNav 200 puts the cursors position into the first available waypoint number. In the example screen shown at right, the cursor is placed at the desired location. Pressing the WPT twice causes waypoint number two to be placed at the cursors crosshairs.
(See the screen at the top of the next page.) A message appears on the display telling you the waypoint number it just used. Wait a few seconds and the menu will clear automatically. Press the
EXIT key to erase the cursor. Saving Your Present Position as a Waypoint (Select Number Method) The method shown above doesnt let you choose the waypoint number. You can pick the waypoint number, then save your present position. To do this, first press the WPT key once. A screen similar to the one at right appears. Now press the up arrow key once. This is the waypoint number selection menu. Press the left or right arrow keys until the waypoint number appears that you wish to store your present position. In this example, were going to store a position as waypoint number 6. Now press the down arrow key until the WPT Options label is highlighted. Press the right arrow key. A screen similar to the one shown at right appears. Highlight the SaveWPT As label (shown at the bottom of the menu) and press the right arrow key when youre at the location you wish to save. This saves your present position under the waypoint number you selected on the first page. Saving Cursor Position as a Waypoint

WPT 2 in waypoint 5s name field. DISTANCE BETWEEN WAYPOINTS The GlobalNav 200 can easily give you the distance between two user waypoints. To do this, first press the WPT key, highlight the Options menu and press the right arrow key, then highlight the Dist Btwn WPTS label and press the right arrow key. The screen at right appears. The black box is resting on the WPT B label. Now press the down arrow key to highlight the waypoint number label. Press the left or right arrow keys until the desired waypoint appears in the WPT B box. Once you have the first waypoint showing on the screen, then you need to choose the other waypoint that youre going to measure. Move the black box back to the Select label at the top of the screen, then press the left arrow key to select A. Now choose the waypoint that you wish to measure. The distance and bearing from the first waypoint A to the second waypoint B shows at the bottom of the screen. You can select more waypoints to measure at this time or press the EXIT key to erase this screen. WAYPOINT OPTIONS You can customize the look of the waypoints on the plotter, or even turn them off. To do this, first press the MENU key, then highlight the WPT/ Icon Opts label. Press the right arrow key. The screen shown at right appears. To keep the waypoints from showing on the plotter, simply press the right arrow key when the Waypoints label is highlighted. To change the method waypoints show on the plotter, highlight the SHOW WPT label. The default is numbers. In other words, when the waypoint shows on the plotter, its number appears in a box, showing both its identity and location. You can change this from number to name, or simply an empty box (position) showing no identifiable name or number by pressing the left or right arrow keys until the desired method appears. Now press the EXIT key. This erases the menu and returns to the plotter with your selection.
Delete a Waypoint To erase all of the information in a waypoint, first press the WPT key, then select the waypoint you want to erase. Now highlight the Options label and press the right arrow key. Finally, highlight the Delete WPT label and press the right arrow key. A message appears, asking if you really want to delete this waypoint. Press the right arrow key to delete it, the left to exit without deleting the waypoint.
ROUTES You can connect several user waypoints together to form a route. When you recall the route, the GlobalNav 200 will show you navigation information to the first waypoint in the route, then when you reach that waypoint, it switches to the next waypoint, and so on until you reach the last waypoint in the route. To create a route, first press the MENU key, highlight the PLAN/EDIT ROUTES label, and press the right arrow key. The screen shown at right appears. This unit can store up to 99 different routes. Route number one shows on this page. If you wish to create a route using a different number, simply press the left or right arrow keys until the desired route number appears. In this example, however, well use route number one. At the bottom of this menu is the Edit Name label. If you wish to name the route, highlight that label, then press the right arrow key. Use the arrow keys to name the route, (you can use up to eight characters in the name) then press the ENT key when youre finished. To add waypoints to the route, highlight the Edit Route label and press the right arrow key. The screen shown at the top of the next page appears. This is the waypoint list screen. This shows all of the waypoints that form

SYSTEM SETUP The GlobalNav 200 has several menus and commands listed under the System Setup label on the main menu. These commands affect the basic operation of the unit. To use them, press the MENU key, then highlight the System Setup label. Press the right arrow key. The screen shown at right appears. BACKLIGHT The GlobalNav 200s display has lights that can be turned on for night use. To turn the lights on, simply press the PWR key. To turn them off, press the PWR key again. An indicator on the satellite status screen (Group O) shows when the lights are on. The GlobalNav 200 automatically turns the lights off after 30 seconds to preserve the battery power. It will do this even if the external power is applied to the unit. The time delay is adjustable from 5 to 240 seconds. You can also turn the lights on continuously from this menu. Use the Light Dly (light delay) menu to change this. Highlight this menu, then press the right arrow key to increase the time the lights are on, the left arrow key to decrease it. Press the EXIT key to erase this menu. SOUND To turn the speaker off, highlight the SOUND label as shown above, then press the left arrow key. Note: This turns the speaker completely off. The unit will not sound a tone when a key is pressed, nor will any alarm sound. The alarm messages will still flash on the screen, however. CONTRAST To adjust the displays contrast, highlight the Contrast label on the System Setup menu as shown above. Press the right or left arrow keys until the screens contrast is best for the lighting conditions. Press the EXIT key to erase this screen.
Units of Measure The GlobalNav 200 can show its data in many different formats. For example, distance can be displayed in statute miles (MI), nautical miles (NM), or kilometers (KM). The following can be changed on the Change Units menu: (Defaults shown in bold) Clock.. 12-hour (a.m.-p.m.), 24 hour Distance.. miles, nautical miles, kilometers Speed. miles per hour, knots, kilometers per hour Bearing. magnetic, true Altitude. feet, meters To change a unit of measure, first select the Change Units label from the System Setup menu. The screen shown above appears. Highlight the desired selection, then press the left or right arrow key. You can change any or all of the settings on this page. When youre finished, press the EXIT key. NMEA / DGPS The GlobalNav 200 transmits data through the data port in the back of the unit using NMEA 0183 format, version 1.5 or 2.0. This data is used by other electronic devices such as marine autopilots for position and steering information. DGPS on the other hand, is a data input. DGPS is an acronym for Differential Global Positioning System. Currently, it relies on a system of groundbased transmitters that send correction signals to small DGPS receivers. DGPS gives you more accurate positions than is otherwise possible. All wiring connections to the GlobalNav 200 are made to its power cable. See the sample wiring diagrams on the next page for general wiring procedures. Read your other products owners manual for more wiring information. Once the cables are wired, turn the GlobalNav 200 on, press the menu key, and select NMEA / DGPS from the System Setup menu. A screen similar to the one at right appears.

Configure NMEA Output Highlight the Configure NMEA Output menu, then press the right arrow key. A screen similar to the one at right appears. NMEA 0183 Version There are two versions of the NMEA data, 1.5 and 2.0. If your other equipment requires 2.0, press the right arrow key to select it. GLL, RMC/RMB, APB, GGA, GSA/GSV Sentences Some equipment requires different sentence. The GlobalNav 200s default setting for these sentences is on. In other words, it automatically sends these sentences when NMEA is turned on. To turn any of these off, move the black box to the desired menu and press the left arrow key. Press the EXIT key when everything on this screen is the way you want it. DGPS The GlobalNav 200 will recognize Starlink and Magnavox automatic DGPS receivers. If you have either one of these receivers, simply highlight the Star DGPS or Magn DGPS on the NMEA / DGPS menu and press the right arrow key to turn it on. (Note: If you have a Magnavox DGPS receiver connected, the GlobalNav 200 cant send NMEA data.) With the exception of serial communications, typically no other setup needs to be made with these receivers. If you have any other Magnavox or Starlink compatible DGPS receiver connected to the GlobalNav 200, you may need to change the settings. To do this, move the black box to the Configure DGPS label and press the right arrow key. A screen similar to the one at right appears.

These menus select the beacon receivers frequency and bit rate (in bits per second). To change one of these settings, simply highlight the menu item you wish to change, then press the right or left arrow key until the desired number appears. Press the EXIT key when youre finished. SERIAL COMMUNICATIONS SETUP To set the data port, move the black box to the Com Port Setup on the System Setup menu. Press the right arrow key. The screen shown at right appears.

Press the EXIT key when youre finished reading this screen.
GPS SETUP The GPS Setup menu has sub-menus that affect the GPS receiver. From these menus you can set the update rate, initialize the GPS receiver, do a self-test on the receiver, and do a cold-start. (Note: The Initialize GPS receiver is covered in the Finding Your Position section in the front of this manual. To view these menu items, press the MENU key, then highlight the GPS Setup menu. Press the right arrow key. The screen at right appears. GPS Cold Start When the GlobalNav 200 is turned on for the first time out of the box, it automatically sends a cold-start message to the GPS receiver. You can also send a cold start message to the receiver at any time. If the unit cant lock on to the satellites using the data youve given it, or if it has trouble finding the satellites, perhaps it is using the wrong data. This can happen if youve entered the wrong data by accident when initializing the receiver. For example, if you entered east longitude instead of west. Or if youve moved a long distance with the unit turned off. To send a cold start message to the receiver, highlight the GPS Cold Start label, then press the right arrow key. A message appears, asking you if you really want to do a cold start. Follow the instructions on this message page. The unit will begin searching for the satellites. It can take as long as 5 minutes for it to lock on to the necessary satellites. Remember, when it does, your local time and possibly date can be wrong. Use the method shown in the initialization section at the front of this manual to change them, if needed. Once this is done, an internal clock will keep the correct time, even when the unit is turned off. The GPS system updates this clock when the unit is locked on to the satellites.

OPERATION

Turning Power On To turn the GlobalNav 310 on, simply press the PWR key. A screen similar to the one at right appears. Read the message on the screen, then press the EXIT key to erase it. The GlobalNav 310 is now ready for use.
MENUS Most of the Lowrance Views adjustments and features are found on menus. Pressing the MENU key lets you view the menus. Different menus items are added to the basic list, depending on which mode (plotter, navigation, or windows) the unit is in. This gives you the features that are specific to the mode you are in, but also has items that are used on all modes. Using the arrow keys moves the black box to highlight different menus on the list. Pressing the right arrow key selects the menu. To erase a menu, press the EXIT key.

Finding Your Position

Cold Start When the GlobalNav 310 is turned on for the very first time, it doesnt know where it is, nor what the local time or date is. If you tell it your position, time, and date, the unit will take much less time to lock-on to the satellites and give you a fix or position. However, if you dont want to push buttons at this time, thats fine. The GlobalNav 310 will lock onto the satellites and give you a position without any input from you. This is called a cold-start. It simply means that the unit is searching without help for the satellites that are in orbit. A coldstart can take up to 2 minutes to acquire enough satellite data to determine your position, although it typically takes less time than that.
Once it locks on to the satellites and finds your position, it stores the satellite data in its memory. The next time you use the unit, it should take much less time to lock on. To use your GlobalNav 310, first make certain you have a clear view of the sky, free from any obstructions such as trees, carport, or a covered boat dock. Press the PWR key. Read the message on the screen, then press the EXIT key to erase the message. A screen similar to the one at right appears. This is windows group A. Your track (TRK), or direction of travel is shown in the upper right corner of this screen. Bearing to a waypoint (BRG), Course over ground (CRS), and cross track error (XTK) are all shown on this screen. You must recall a waypoint to use the bearing, course, and cross track error windows. As you wait for it to find your position, youll see numbers flashing on the display. Anytime you see flashing numbers, it means the GlobalNav 310 does not have a position! Do not rely on any data that is flashing! When the numbers stop flashing, the unit has locked on to the satellites and the position is good. Thats all you have to do to find your position. All time displays may not be correct when the cold start method is used. See the initialization section for details on changing the time.

Nav Screen #2 The navigation screen shows navigation information in large digital numbers. To view this screen, press the MODE key, then press the up arrow key until the black box surrounds the NAV 1 label. Now press the right arrow key. A screen similar to the one at right appears. Press the EXIT key to erase the mode menu. This screen is composed of eight digital display boxes, showing your track (TRK), and ground speed (GS). The other boxes show navigation data when a waypoint is recalled, including bearing to the waypoint (BRG), course (CRS), Altitude (ALT), distance to waypoint (DIS), velocity made good (VMG), and cross track error (XTK). Plotter The plotter lets you see your course and track from a birds-eye view. If youve recalled a waypoint, the plotter show your staring location, present position, and destination. However, you dont have to recall a waypoint to use the plotter. To use the plotter, simply press the MODE key, then press the up or down arrow keys until the Plot label is higlighted. Press the EXIT key to erase the mode menu. A screen similar to the one at right appears. This is plot-1. The diamond flashing in the center of the screen is your present position. The solid line extending from the diamond is your track, or path youve travelled. The plotters range is shown in the lower left corner of the screen. In this example, the plotters range is two miles from the left edge of the screen to the right. There are two different plotter screens available. Map screen number 1 shows by default. Your current position displays at the center of the screen by a cross surrounded by a flashing diamond. To view the other plotter screen, press the MODE key. Press the up or down ar14
row key to move the black box to the "PLOT" label. Now press the right arrow or left arrow key to select plot 2. This screen (as shown at the bottom of the previous page) has navigation data displayed on the right side of the screen in digital numbers. This data is active whenever youve recalled a waypoint. Press the EXIT key to erase the mode menu. This screen shows ground speed (GS), track (TRK), course (CRS), and cross track error (XTK). Use the Z-IN and Z-OUT keys to enlarge or reduce the plotter area. This changes the plotters range. The available ranges are: 0.1, 0.15, 0.2, 0.3, 0.4, 0.6, 0.8, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 15, 20, 30, 40, 60, 80, 100,150, 200, 300, 400, 600, 800, 1000, 1500, 2000, 3000, and 4000 miles. Cursor Pressing an arrow key while the plotter is on shows two dotted lines that intersect at your present position. These dotted lines are called a cursor and have a variety of uses. You can move the cursor around the display by pressing the arrow keys in the direction you want it to move. This lets you view different areas of the plotter, away from your present position. When its turned on, the zoom-in and zoom-out keys work from the cursors position - not the present position, so you can zoom in on any detail, anywhere while navigating. The latitude/longitude of the cursor shows in the box at the top of the plot-1 screen whenever the cursor is activated. The cursor is also used to place and erase icons and waypoints. Press the EXIT key to erase the cursor.

PLOTTER OPTIONS The GlobalNav 310 lets you customize the plotter using the plotter options menu. To use this menu, first press the MENU key, then use the up or down arrow keys to highlight the Plotter Opts label. Finally, press the right arrow key. The screen shown at right appears.
Record Trail On / Off The line extending from the present position diamond on the plotter is call the plot trail. As each dot on the trail is placed on the screen, its also saved in memory. The plot trail recording can be turned off, if desired. To turn it off, press the up or down arrow key until the Record Trail menu is highlighted and press the left arrow key. Press the EXIT key to return to the main menu. Clear Current Plot Trail To erase the plot trail extending from your present position, highlight the ClearPlot Trail menu, then press the right arrow key. A message box appears, asking you if you really want to erase the plot trail. Follow the directions on this message box. The GlobalNav 310 returns to the plotter screen after the message box clears. Plotter Orientation Normally, the GlobalNav 310 shows the plotter with north always at the top of the screen. This is the way most maps and charts are printed on paper. This is fine if youre always travelling due north. Waypoints you see to your left corresponds to the left side of the plotter, to your right is shown on the right side of the plotter, and so on. However, if you travel any other direction, the plotter doesnt line up with your view of the world. To correct this problem, this unit has a track-up mode that rotates the plotter as you turn. Thus, what you see on the left side of the screen should always be to your left, and so on. It also has a course-up mode that keeps the plotter at the same orientation as your initial bearing to the waypoint. In the examples shown at right and on the next page, we're travelling southeast (about 210 magnetic). In the north-up view (at right), the present position indicator appears to move towards the lower left corner of the screen. The anchor icon shown on the left side of the screen is actually on our right. North is always at the top center of this screen.

NORTH-UP MODE

In the track-up view at right, the present position moves straight towards the top of the display. As you can see, the anchor icon is now shown in its proper orientation - to our right. A "N" shows to help you see which direction is north when the track-up mode is on. Remember, in the track-up mode, the screen rotates as you change direction. It always keeps your direction of travel (track) heading towards the top of the screen. In the course-up mode shown at right, the screen is locked into your original bearing to the recalled waypoint, regardless of your track. To select the desired mode, highlight the ORIENTATION label on the Plotter Options menu, then press the left or right arrow keys until the desired mode appears. Press the EXIT key to leave this menu

TRACK-UP MODE

COURSE-UP MODE
Plotter Update The plotter places a dot on your trail as you move. It determines when to place a dot depending on either time or distance. By default, it places a dot every three seconds. To change the update method from time to distance, highlight the Update By label, then press the right arrow key. This moves the label from TIME to DIST. If you want to change the update time or distance, simply highlight the desired menu, then press the left or right arrow keys until the desired setting appears. Press the EXIT key to return to a navigation, plotter, or windows screen.
Grid Lines The GlobalNav 310 can place grid lines on the plotter to help you see your position, or the position of waypoints and icons. To do this, highlight the Grid Lines label on the Plotter Opts menu, then press the right arrow key to turn them on. Press the EXIT key to exit this menu. A plotter screen similar to the one at right appears. The grid lines appear as vertical and horizontal dashed lines. ICONS The GlobalNav 310 has fifteen symbols or icons available. These icons can be placed anywhere on the plotter screens. These can be used to mark fishing spots, boat ramps, rest stops, or whatever. You can place an icon at your present position, or at the cursor location. Place Icon - Present Position To place an icon at your present position, simply press the ENT key. The screen shown at right appears. Use the arrow keys to move the black box to the desired icon. Now press the ENT key. The plotter screen appears with the icon you selected placed at your position when you first pressed the ENT key, not your present position.
Place Icon - Cursor Location To place an icon at cursor's location, first use the arrow keys to move the cursor to the position that you want to place the icon, as shown at right. Next, press the ENT key. Now select the desired icon using the arrow keys. When it's selected,
press the ENT key. The plotter screen reappears with the icon at the cursor's location. Press the EXIT key to erase the cursor. On the screen shown at right, the large fish icon was selected and placed at the cursor location.
Erase Icons To erase an icon from the screen, first press the MENU key, then select the WPT/Icon Opts menu. A screen similar to the one at right appears. There are three methods used to erase icons from the screen. You can delete all of the icons, regardless of their position on the display, delete all of the icons of a certain type, or selectively erase individual icons. To erase all of the icons, highlight the Delete All Icons menu, then press the right arrow key. A message appears, asking you if you want to delete all icons. Press the right arrow key to erase them. The unit returns to the plotter screen with all icons deleted. To remove only icons of a certain type, highlight the Delete Icons By Type label. Press the right arrow key. The icon selection menu appears. Use the arrow keys to highlight the icon style that you wish to erase. Press the ENT key when youre ready to erase the icons. A message appears, asking you if you want to delete the icons of that type. Press the left arrow key to erase them. The unit returns to the plotter screen with all icons of the type you selected erased. To remove only certain icons, highlight the Delete Icons From Plotter label. Press the right arrow key. The unit returns to the plotter screen with the cursor centered on your present position as shown at right. Use the arrow keys to move the cursor to the icon on the map that you wish to erase. Press the ENT

Select Waypoints Select the first waypoint either by using the waypoint name or waypoint number menus. As you move through the list of saved waypoints, their date and time saved, position, and distance and bearing from your present position show at the bottom of the screen. When the desired waypoint appears that you want to use as the first waypoint on the route, move the black box to the Add WPT To Route label, then press the right arrow key. The unit returns to the route planning screen with this waypoint placed in the first location on the list as shown at right. To add more waypoints to the route, simply press the down arrow key to the next position on the list and press the right arrow key. Continue until all of the waypoints have been added to the route. As you add waypoints to the list, their bearing and distance from each other is shown to the right of the waypoint name. On the screen at right, waypoint 6 is on a bearing of 215 and 7.27 miles from waypoint 3. The total route distance is shown at the bottom of this screen.
Finishing the Route When youve selected all of the waypoints for the route, simply press the EXIT key until you return to the navigation, plotter, or windows screen. Your route is saved in memory. Delete a Waypoint To delete a waypoint from a route, first select the route from the Route Planning or Run Route menus, then highlight the waypoint that you want to remove from the routes list. Now press the right arrow key. The screen shown at right appears. Highlight the Delete label on this menu and press the right arrow key. The unit returns to the route list with the waypoint removed from the list. (Note: This doesnt delete the waypoint from the database, it only removes it from the route.) Waypoint Detail To view the position, bearing, distance, and other information about a waypoint saved in a route, first select the route from the Route Planning or Run Route menus, then highlight the desired waypoint from the routes list. Now press the right arrow key. The screen shown above appears. Move the black box to the Detail label and press the right arrow key. The screen at right appears. This screen shows the waypoints name, number creation time and date, icon, position, distance, and bearing from your present position. When youre finished viewing this information, press the EXIT key to erase it.
Following a Route To follow a route, first recall it by pressing the MENU key, highlighting the ROUTES label, pressing the right arrow key, then highlighting the RUN ROUTE label and press the right arrow key. The screen shown at right appears.

The black box is on the Route # 1 label. If this isnt the route you want to use, press the right or left arrow keys to switch to another one. Before starting the route, youll need to decide if you want to start at the beginning and travel forward or start at the last waypoint in the route and travel backwards (reverse) to the first waypoint. The default is forward. Next, highlight the Start Route label and press the right arrow key. The screen shown below appears. Once you determine which direction in the route you want to go, youll need to determine the first waypoint in the list you want to start the route. Usually, its the first waypoint, however the GlobalNav 310 gives you several options. The default starting waypoint is the first one in the list. However, by pressing the right arrow key, the word AUTO appears in the Select First WPT list. This starts the route with the waypoint thats closest to your present position. You can start at any waypoint in the route. As you change the number, the selected starting waypoint is highlighted on the list. If you want to see details about the highlighted waypoint, press the WPT key. When you have everything on this screen set as desired, press the ENT key to start the GlobalNav 310 navigating to the first waypoint on the route. As you travel to the first waypoint, the unit shows navigation data to the waypoint. If you use the plotter, as shown at right, the unit draws a dotted line from your starting position (shown by the S), and a dashed line from the first waypoint to each of the other waypoints in the route. When you enter the radius set by the arrival alarm, the GlobalNav 310 automatically switches to the next waypoint on the list, showing navigation data to that waypoint, and so on until the last waypoint on the route list has been reached. (Note: The arrival alarm does not have to be turned on in order to use the route feature.)
Skip Waypoint The GlobalNav 310 lets you skip a waypoint in a route without stopping the route. To do this, first press the MENU key, then highlight the Routes menu and press the right arrow key, then highlight the Skip WPT label and press the right arrow key. The unit returns to the navigation, plotter, or windows screen with navigation data showing to the next waypoint on the list. Delete a Route To erase a route, first press the MENU key, then highlight the Routes menu and press the right arrow key, highlight the Plan Route label and press the right arrow key. The screen shown at right appears. Now select the route you want to erase by pressing the right or left arrow keys. When the desired route number appears, then highlight the Delete Route label and press the right arrow key. A message appears, asking if you really want to erase the route. If you press the right arrow key, the route will be erased.

SYSTEM SETUP The GlobalNav 310 has several menus and commands listed under the System Setup label on the main menu. These commands affect the basic operation of the unit. To use them, press the MENU key, then highlight the System Setup label. Press the right arrow key. The screen shown at right appears.
SPEAKER You can turn the speaker off. Turning the speaker off also turns off the audible portion of the alarms. To turn the speaker off, highlight the Sound label on the System Setup menu as shown above. Now press the left arrow key to turn the speaker off. Repeat these steps to turn the speaker on. Press the EXIT key to erase this screen. CONTRAST To adjust the displays contrast, highlight the Cont label on the System Setup menu as shown above. Press the right or left arrow keys until the screens contrast is best for the lighting conditions. Press the EXIT key to erase this screen. Units of Measure The GlobalNav 310 can show its data in many different formats. For example, distance can be displayed in statute miles (MI), nautical miles (NM), or kilometers (KM). The following can be changed on the Units of Measure menu: (Defaults shown in bold) Distance. miles, nautical miles, kilometers Speed. miles per hour, knots, kilometers per hour Bearing. magnetic, true Altitude.. feet, meters Clock.. 12-hour (a.m.-p.m.), 24 hour Position Format. degrees, minutes, and thousands of a minute degrees, minutes, seconds UTM standard military grid reference system alternate military grid reference system
To change a unit of measure, first select the Set Units from the System Setup menu. The screen shown at right appears. Highlight the desired selection, then press the left or right arrow key.You can change one or all of the settings on this page. When youre finished, press the EXIT key.
Position Format To change the position format, highlight the Position Format label on the Units of Measure menu, (shown above) then press the right arrow key. A screen similar to the one at right appears. The GlobalNav 310 can show the position in degrees, minutes, and thousandths of a minute (36 28.700') or degrees, minutes, seconds, and tenths of a second (36 28' 40.9". It can also show position in UTMs (Universal Transverse Mercator) projection, British, Irish, and Military Grid systems. UTMs are marked on USGS topographic charts. This system divides the Earth into 60 zones, each approximately 6 degrees wide in longitude. Their unit of measure is in meters. For example, 30 N means that the position shown to the left of the N is in grid 30, and its north of the equator.

British and Irish grid systems are the national coordinate system used only in their respective countries. Note: In order to use either the British or Irish grid systems, you must be in the U.K.
The GlobalNav 310 can use the military grid reference system (MGRS). It uses two grid lettering schemes, which are referred to as standard and alternate MGRS on the GlobalNav 310. Your position and datum in use determines which one to use. In general, if the datum youre using is valid for your present position, then use the standard MGRS, otherwise use the alternate MGRS. Press the up or down arrow keys to highlight the desired position format. Press the EXIT key to both select the format and erase the position format menu.
NMEA / DGPS The GlobalNav 310 transmits data through the data port in the back of the unit using NMEA 0183 format, version 1.5 or 2.0. This data is used by other electronic devices such as marine autopilots for position and steering information. DGPS on the other hand, is a data input. DGPS is an acronym for Differential Global Positioning System. Currently, it relies on a system of groundbased transmitters that send correction signals to small DGPS receivers. DGPS gives you more accurate positions than is otherwise possible.
All wiring connections to the GlobalNav 310 are made to its power cable. See the sample wiring diagrams on the next page for general wiring procedures. Read your other products owners manual for more wiring information. Once the cables are wired, turn the GlobalNav 310 on, press the menu key, and select NMEA / DGPS from the System Setup menu. A screen similar to the one at right appears. NMEA OUTPUT To turn the NMEA output on, highlight the NMEA OUTPUT menu, then press the right arrow key. If your other equipment works, then no setup will need to be performed. If your other equipment doesnt recognize the NMEA data being sent by the GlobalNav 310 and the wiring is correct, then you may need to change the NMEA or the serial communication settings. Configure NMEA Output Highlight the Configure NMEA Output menu, then press the right arrow key. A screen similar to the one at right appears. NMEA 0183 Version There are two versions of the NMEA data, 1.5 and 2.0. If your other equipment requires 2.0, press the right arrow key to select it. RMC/RMB, GLL, APB, GGA, GSA/GSV Sentences Some equipment requires different sentence. The GlobalNav 310s default setting for these sentences is on. In other words, it automatically sends these sentences when NMEA is turned on. To turn any of these off, move the black box to the desired menu and press the left arrow key. Press the EXIT key when youre finished with this screen. DGPS The GlobalNav 310 will recognize Starlink and Magnavox DGPS automatic receivers. If you have either one of these receivers, simply highlight the Starlink DGPS or Magnavox DGPS on the NMEA / DGPS menu and press the right arrow key to turn it on. (Note: If you have a Magnavox

tializing the receiver. For example, if you entered east longitude instead of west. Or if youve moved a long distance with the unit turned off. To send a cold start message to the receiver, highlight the Execute GPS Cold Start label, then press the right arrow key. A message appears, asking you if you really want to do a cold start. Follow the instructions on this message page. The unit will begin searching for the satellites. It can take as long as 5 minutes for it to lock on to the necessary satellites. Remember, when it does, your local time and possibly date can be wrong. Use the method shown in the initialization section at the front of this manual to change them, if needed. Once this is done, an internal clock will keep the correct time, even when the unit is turned off. The GPS system updates this clock when the unit is locked on to the satellites. DATUM Maps and charts are based on a survey of the area thats covered by the map or chart. These surveys are called Datums. Maps that are created using different datums will show the same latitude/longitude in slightly different locations. All datums are named. The GPS system is based on the WGS-84 datum, which covers the entire world. Other datums may also cover the entire world, or just a small portion. By default, the GlobalNav 310 shows your position on the map using the WGS-84 datum. However, it can show your position using one of 189 different datums. To change the datum, first press the MENU key, then highlight the GPS Setup label and press the right arrow key. Now highlight the Select Datum label. Finally, press the right arrow key again. A screen similar to the one at right appears. The WGS-84 label is highlighted. To change it, simply press the up or down arrow keys to highlight the desired datum, then press the ENT key. This selects the datum and erases the select datum menu.
PCF (Position Correction Factor) Another method used to make your display match a chart or map is called PCF or Position Correction Factor. This unit gives you the capability to move or offset the position shown on the display to match one on the chart. The unit will add this offset to all position and navigation displays at all times. Remember, the position error on any radio navigation system is very dynamic and the PCF offset should never be used in an attempt to cancel the error. In general terms, PCF should only be used if your map indicates what the possible error is. PCF should always be reset to zero when youre finished with the chart. For example, suppose you are stopped at a location that is accurately marked on a chart. Your unit shows a longitude position that is.244 minutes east of the one on the chart and.047 minutes north latitude. Using the PCF feature, you can make the GlobalNav 310 match the chart youre using. If you move, the unit will continuously add the change to all position, navigation, and mapping displays. This makes it more closely match the datum used by the chart. For this reason, you should be careful when entering the PCF offset. Its saved in memory and doesnt change when the unit is turned off. However, resetting the unit does erase the PCF offset. To change the PCF offset, first press the MENU key, then highlight the GPS Setup label and press the right arrow key. Now highlight the Set PCF Offset label. Finally, press the right arrow key again. A screen similar to the one at right appears. Now enter the correction for your location. Remember, this is the difference between the location shown on the present position display and the position shown on the chart. In this example, we entered 0 degrees, 0.047 minutes north latitude and 0 degrees, 0.244 minutes east longitude. That is the difference between the present position shown by the GlobalNav 310 and the one on our chart.

MESSAGES On the GPS Alarms menu are the position and DGPS message selections. When turned on, the position message appears for a few seconds whenever the GlobalNav 310 locks onto the satellites and shows a position. It also appears when the unit loses the lock onto the satellites and cannot navigate. Pressing the EXIT key erases these messages. The DGPS message appears whenever the unit begins or stops using DGPS data to help determine your position. The default setting for these messages is on. To turn either message off, select the GPS Alarms menu from the main menu, then move the black box to the desired message and press the left arrow key. Press the EXIT key to erase this screen. BACKLIGHT The AirMaps display and keyboard have lights that can be turned on for night use. To turn the lights on, simply press the PWR key. To turn them off, press the PWR key again.
REPROGRAM WINDOW GROUPS You can customize the window groups to meet your own needs. The GlobalNav 310 gives you 35 different windows that can be rearranged into many combinations.
