DGPS BEACON RECEIVER CONNECTIONS If a Lowrance GPS module is connected to the GlobalMap 2000, any brand of differential (DGPS) beacon receiver can also be connected, giving you higher accuracy positions in the area covered by the beacon receivers. The unshielded green and white wires on the POWER cable are used for the differential (DGPS) beacon receiver. (Note: You can also use the diagram on pages 7 or 8 if youre using a Lowrance DGPS receiver.) To connect the beacon receiver, attach a twisted pair cable from the beacon receivers output to the green and black wires (unshielded) on the mapping units POWER cable as shown below. Solder the ground conductor of the twisted pair to the black wire on the power cable. If needed, also attach a twisted pair cable from the beacon receivers input to the white and black wires on the mapping units POWER cable. (Not all beacon receivers require an input.) After the beacon receiver is connected, see the GPS/DGPS Setup section for information on setting the communication parameters for the DGPS receiver.

how strong the satellites signal is. The higher the SNR number, the better. To exit this screen, press the MAP, NAV, STEER, or SONAR keys. DGPS BEACON RECEIVER STATUS With both a Lowrance GPS module and a DGPS beacon receiver connected to the GlobalMap 2000, then DGPS receiver status shows on the status screen. Again, to view this screen, press the MENU key, the press the key next to the Status label. A screen similar to the one below appears. The status of the DGPS receiver shows at the screens top right side. If the mapping unit is receiving good data from the DGPS receiver, the word Operational appears at the top of this screen. Next are shown the station identification (ID), station frequency (Freq), station data transmission rate (Rate), signal-to-noise ratio (SNR), signal strength (Sig), and age status (AGE). At the very bottom of the screen are the DGPS statistics (DGPS). An OK in this field means that the DGPS corrections for that satellite are good. A blank in this field means that there is no corrections for that satellite. To exit this screen, press the MAP, NAV, STEER, or SONAR keys. MAP OPERATION MAPPING/NAVIGATION/STEERING/SONAR DISPLAYS This mapping unit has mapping, navigation, steering indicator, satellite information and sonar screens. These displays were designed to show the most important data. However, you can change all of them (except the satellite information) to some extent through the Customize Display feature on the second GPS menu screen. To change these screens, see the Customize section in this manual. Each of the following screens is available by pressing a key at the bottom of the unit. A detailed description of each screen follows.
IMPORTANT! If the data shown in digital numbers on any screen on this unit is flashing, then it means that data is invalid. Do not rely on data that is flashing! For example, if the present position display is flashing, then the unit has lost the position data from the GPS module or NMEA 0183 data input. The position that is flashing is the last known position, not your present position! Do not navigate with this unit until you have found the reason the unit has lost the position data!
MAP SCREEN The Map screen automatically appears the first time the GlobalMap 2000 is turned on and after a preset. You can also view this screen at any time by pressing the MAP key. A screen similar to the one at right appears. Your present position appears as a circle with a cross on the screen. The latitude/longitude of your present position shows at the bottom of the screen. Each time you switch to this screen, it centers your present position and the map on the display. To zoom in for a closer look, press the ZOOM IN key in the upper left corner. To zoom out and see a wider area around your present position, press the ZOOM OUT key. The range, or approximate distance from one side of the screen to the other is shown in the lower right corner of the map. Each time you press the ZOOM IN or ZOOM OUT key, the range changes, typically showing you more detail when youre zoomed in or a wider area when youve zoomed out. As you travel, the circle showing your present position moves on the screen, too. The line extending from the circle shows the path youve taken. Pressing the MAP key once while the map is displayed causes the whole display to be used by the map as shown at right. The digital boxes disap29

time to move the cursor lines diagonally. In the screen shown on the previous page, the cursor lines are 1.08 miles and 149 degrees from the present position. Note: The cursor is not available when the map is in the course up mode. If you press the CENTER key while the cursor lines are displayed, the unit will center the map at the position of the cursor lines - not the present position. If you want the GlobalMap 2000 to show navigation information to the cursor lines, first move the cursor lines to the desired location, then press the WAYPT/ROUTE key. Now press the key next to the Navigate to Cursor Position label. The GlobalMap returns to the mapping screen with navigation data showing in the digital boxes. A dotted line appears on the map from your present position to the cursor, showing the shortest, most direct line to the cursor position. A box with the letter S appears at the location you were in when you pressed the Navigate to Cursor Position label. The cursor position is marked by a small box and the letters XX which remain on the screen, even if you turn the cursor lines off. For more information, see the waypoint navigation section. To turn the cursor lines off, simply press the CURSOR key. PLOTTER TRAIL Your present position marker leaves a line or trail behind as it moves across the map, according to the boats movement. This makes it easy to see the path youve taken. There are two ways to customize the trail plotter. First press the MENU key. Now press the key next to the Trail Plotter label. The screen shown at the top of the next page appears. There are

Plotter Trail

seven menu selections on this screen, all of which relate to the trail plotter. After youve made a selection on this screen, press the CLR key to exit. Clear Trail The first item at the top of the screen is Clear Trail. This erases the plot trail from the screen. This is only temporary, the GlobalMap 2000 will continue to draw your trail from the location it was in when the key next to the Clear Trail label was pressed. If you wish to change the plot trail from a solid line to a dotted one, then press the key next to the Trail Type label until the check mark is on the desired box. Trail Recording and Display To stop the GlobalMap 2000 from drawing the plot trail, press the key next to the Trail Recording label. The GlobalMap 2000 not only will stop drawing the plot trail, but also will not keep track of it in memory. However, it will show your trail on the map up to the point that you turned it off. If you wish to temporarily stop the plot trail, but wish to resume its display at a later time, showing the path youve taken, then press the key next to the Trail Display label. This turns the plot trail off, but its still kept in memory. If you turn the trail display on again, it will show your entire plot trail (if theres enough memory.) Theres a maximum of 2000 dots available to plot a trail. Plot Trail - Distance Interval Theres a certain amount of memory reserved for the plot trail. If the unit runs out of memory, then it will continue to draw the plot trail, but for every dot it places at the end of the trail, it will erase one at the beginning. When the unit is turned on for the first time, the units plot trail settings are optimized for the typical user. The trail is recorded by the distance travelled, which is preset to draw one dot every 0.001 mile. In other words, every time you move.001 mile, the unit places a dot on the trail behind your present position. The distance can be changed from 0.001 to 10 miles by pressing the key next to the Distance Interval menu. The number at the far right of that label shows the distance interval currently in use. Once you press the key next to that label, a new menu appears. Press the key next to the desired distance interval. The unit returns to the Trail Plotter menu.

digital boxes on this screen are customizable. Press the STEER key to view this screen. Your present position is shown by the arrow. The arrow shows the direction the boat is heading relative to the waypoint. In theory, if you steer the boat with the arrow always pointing towards the waypoint, then you will arrive at the waypoint. The solid line extending from the arrow is your track or path youve taken. To travel directly to a waypoint, try to keep the arrow on the center line. The waypoint is depicted by a circle at the top of the CDI display. As you approach the waypoint, the arrow and the box will move closer together. If you travel past the waypoint, the waypoints box will move to the bottom of the display. Using the digital displays at the bottom of the screen with the graphical display at the top let you accurately steer the boat to a waypoint. The numbers immediately below the C.D.I. are the C.D.I. range in miles. This gives you an idea of how far off course you are. For example, if the arrow is halfway between the course line and the outside left line and the C.D.I. range is 0.5 miles, then your cross track error is to the left 0.25 miles. The C.D.I. range can be changed from.1 miles to 10 miles. Compare the map screen shown at the bottom of the previous page with the steering screen at the top of that page. The picture of the steer screen and the map screen were taken at the same time. You can see the cross track error, track, distance to waypoint, and the direction you need to steer to the waypoint easily. C.D.I. Range To change the C.D.I. range, press the MENU key, then press the key next to the More label. Finally, press the key next to the Steering Range label. The screen shown at the top of the next page appears. Now press the key next to the desired distance. The unit returns to the steering display with the new C.D.I. range.
A faster way to change the C.D.I. range is to simply press the ZOOM IN o ZOOM OUT keys while the steer screen is displayed. Each time you press one of these keys, the C.D.I. range increases or decreases, depending on which key you press. To clear the plot trail on the steering screen, simply press the CLR key. Pressing the STEER key at the bottom of the unit while the steering screen is displayed changes all of the boxes shown at the top of the display. Again, all of these displays can be changed or rearranged in virtually any combination.
CUSTOMIZE SCREENS The digital displays on the mapping, navigation, and steering screens, plus the displays on the sonar screen can be changed as desired. To show how this is done, well use the Navigation screen as an example. To customize the Navigation screen, first make certain it is showing by pressing the NAV key. Next, press the MENU key two times. Now press the key next to the Customize Display label. The unit returns to the Navigation Screen with an arrow pointing to the top left hand corner box as shown below. In this case, the arrow is pointing to the D.T.G. box. The arrow identifies the box as ready for change. To move the arrow to a different box, simply press the arrow keys until its pointing to the desired box. In this example, the distance to go (DTG) is changing to the estimated time of arrival (ETA) display. With the arrow pointing to the DTG box, press the ENT key. The screen shown at the top of the next page appears. Using the arrow keys, move the arrow to the E.T.A. box. (If the digital box you want is not on this screen, press the MENU key until you see it.

There are four pages of different digital boxes to choose from. Pressing the MENU key changes to the next page.) Once the arrow is pointing to the desired box, press the ENT key. This returns the unit to the screen youre changing (in this example, its the navigation screen), and places the new box on the screen as shown above right. Compare the navigation screen on the previous page with the one below right. To change another box, simply repeat the above steps. When youre finished customizing the screen, simply press the CLR screen. This erases the arrow from the display and locks in your changes. These changes are held in memory and are saved even if power is turned off. Since the Navigation and Steering screens have two different sets of digital boxes available, you can customize each set with different digital boxes, then switch between the screens by simply pressing the appropriate key. For example, customize the navigation screen with one set of digital boxes as shown above. While the navigation screen is showing, press the NAV key. This shows a different set of digital boxes which can also be customized.

NAVIGATION SCREEN

WAYPOINT NAVIGATION HOW TO SAVE A WAYPOINT Waypoints are locations on the earths surface that you wish to go or return to. Waypoints are useful for marking shipwrecks, hot fishing spots, buoys, and other fishing or navigation locations. Storing waypoints makes it easy to return to any point in the world by simply pressing a few buttons. The GlobalMap 2000 can store up to 250 waypoints. You can store your present position or the cursor position as a waypoint or enter latitude/ longitude positions as waypoints. (Quick Save Feature) You can save your present position as a waypoint with only one key press. This Quick Save feature lets you easily save the position of a wreck or other locations. To save your present position as waypoint, simply press the WAYPT QUICKSAVE key. The first available waypoint number is stored with the present position. The unit displays the waypoint on the map and stores the position in the waypoint list. The number shown on the map is the number assigned to it on the waypoint list. See below for more information on storing waypoints. Waypoint Save - View and Save Method The Quick Save feature doesnt let you select the waypoint number. You have to use the next available number when using that method, plus you can only save your present position. The View and Save method gives you far more options. (Note: You can store a position under a waypoint number that already has a position assigned to it using this method.) To save a location as a waypoint, first press the WAYPT/ROUTE key. A new menu appears. Now press the key next to the Waypoints label. The screen shown at the top of the next page appears. The list of waypoints shows on the right side of the screen. The first waypoint number in the list appears at the top of the page. Its highlighted by a black box. This is the number that the position will be stored under. To switch to a different number, simply press the down arrow key. If the

waypoint says Empty, then you can store a position there. A row of menu labels appear on the left side of the screen. Pressing a key next to these labels let you save your present position, the cursor position, select a waypoint destination, edit the waypoint elements, and erase a waypoint from the list. The steps required to save a waypoint, either your present position, cursor position, or any other position are the same. To save a waypoint, first move the black box to the waypoint number you wish to save the location in by using the up or down cursor keys. Now simply press the key next to the Save Present label to save your present position. To save the position at the cursor cross marks, press the key next to the Save Cursor. If you wish to enter a location other than these, press the key next to the Edit Waypt label. You can also change anything on an existing saved waypoint by using the Edit Waypt label. Editing a Waypoint After youve pressed the key next to the Save Present, Save Cursor, or Edit Waypt labels, a new screen appears as shown at right. The position at the time you pressed the Save Present or Save Cursor label is shown in the box in the middle of the screen. (No position shows if you pressed the Edit Waypt key on an empty waypoint.) The waypoint number you are currently editing shows at the top of the screen. A question mark flashes in the Name field. If you wish to name this waypoint, enter the letters of the name using the keys on the left side of the screen. For example, to enter the name REEF, first press the CURSOR key until the letter R appears. Now press the right arrow key once to move to the next location. Press the ZOOM IN key until the E appears. Continue in this manner until the waypoint name is completed as shown at the top of the next page. Press the ENT key when youre finished.
Waypoint Symbols If you want a symbol placed on the map, press the down arrow key to the Symbol location on the waypoint screen. The letters on the left side of the screen disappear and symbols appear in the labels. (See below) Press the key next to the desired symbol to assign it to the waypoint number shown at the top of the screen. There are 28 different symbols available. Enter Latitude/Longitude If there is no latitude/longitude position showing, or if you wish to change the position shown on the waypoint screen, press the down arrow key until the first number starts flashing in the latitude field. Now enter the desired latitude. If you need to change the latitude from north to south, press the key next to the S label. After youve made the desired changes to the latitude, press the down arrow key to move to the longitude. Now enter the new longitude. Press the key next to the E or W if you need to change the longitude from west to east or viceversa. Anytime you make a mistake entering a number, simply press the left or right arrow keys to move to the number you wish to change, then enter the correct one. Once everything on this screen is correct, press the ENT key. The unit returns to the mapping screen as shown at the top of the next page. If the waypoint location is within the area shown on the map, a box appears on the map with the waypoints number beneath it. If a symbol was assigned

to the waypoint, the symbol will show on the screen instead of the box. Navigate to a Waypoint To show navigation data to a waypoint location, first press the WAYPT/ROUTE key, then press the key next to the Waypoints label. The screen shown below appears. Select the waypoint by pressing the up or down arrow keys until the desired waypoint is highlighted by the black box. The waypoints position, distance from your present position, and bearing from your position to the waypoint show at the bottom of the screen. Now simply press the key next to the Go To Waypt label. The GlobalMap 2000 returns to the mapping screen. It draws a S with a box around it showing your position when you recalled the waypoint. (See the screen below.) A dotted line extends from this box to the recalled waypoint. This line is the shortest path to the waypoint. If you steer the boat along this line, youll travel directly to the recalled waypoint. Navigation data also appears in all digital displays which show your course over ground (COG), speed over ground (SOG), distance to waypoint (DTG) and much more. Switch to the navigation or steering screens for more navigation information. Cancel Navigation To stop the GlobalMap 2000 from showing navigation data to a waypoint, first press the WAYPT/ROUTE key, then press the key next to the Cancel Navigation label. The unit returns to the last-used map, navigation, or steering screen.
Erase a Waypoint To delete a waypoint from the waypoint list, first press the WAYPT/ROUTE key, then press the key next to the Waypoints label. The screen shown at right appears. Now move the black box to the waypoint that you wish to erase using the arrow keys. Now simply press the key next to the Erase Waypt label. A message appears on the screen that warns you that this waypoint will be permanently erased. If you still wish to erase this waypoint, press the ENT key. The waypoint location will return to Empty. Press the CLR key to return to the map, steer, or navigation screen. WAYPOINT DISPLAY There are a number of options available when showing the waypoint location on the map. You can show all waypoints or turn them off, show only the symbols, names, or number, or any combination of these. To change the waypoint display, first press the MENU key, then press the key next to the Mapping Setup label. Now press the key next to the More. label. The screen shown at the bottom of the previous page appears. Press the key next to the desired option, then press the CLR key to exit this screen. The defaults for this screen are: all waypoints on, waypoint symbols on, waypoint names off, and waypoint numbers on. ROUTES A route gives you the ability to navigate to several waypoints without having to reprogram the unit after arriving at each one. A route consists of two or more waypoints. When you travel on a route, the GlobalMap 2000 shows navigation information to the first waypoint in the route. When you reach the first waypoint, (signalled by the Arrival Alarm), the unit automatically

sequences to the next waypoint. Navigation information is shown to this waypoint and the process repeats. When you reach the last waypoint in a route, the arrival alarm sounds until you turn it off. There are four steps required to create and follow a route. First, you must create and name the route. Next, select the waypoints used in the route. Then determine the starting waypoint. Next, tell the unit to follow the route. Finally, the unit will ask you if you wish to run the route forward or backward. After these steps are completed, the mapping unit will start showing navigation data to the first waypoint on the route. You can create a route from the list of waypoints or directly from the map. CREATING A ROUTE Name a Route To create a route, first press the WAYPT/ROUTE key. Next, press the key next to the Routes label. The screen shown below appears. This menu lets you create a route, edit an existing route, run a route, erase it, and set the auto-sequencing and arrival radius. To create the route, press the key next to the Create Route label. The screen shown at right appears. This is the name route menu. Press a key next to the label that has the desired letter repeatedly until the first letter in the route name appears. Now press the right arrow key once. Select the next letter in the route name, then press the right arrow key again. Continue in this manner until the route name has been entered. (Note: To enter a space, press the key next to the Z ,. label. The space is the character after the Z.) When the name appears as you wish, press the ENT key. The screen at the top of the next page appears.
Waypoint Selection Youre now ready to place the waypoints into the route, using any of three different methods. You can place waypoints using the cursor on the map, from the list of waypoints, or enter the latitude/longitude of each waypoint from the keyboard. IMPORTANT! You must select waypoints in the order they are to be used in the route. In other words, suppose you want a route that consists of waypoint numbers 1, 3, and 5. However, you wish to travel to 3 first, then 1, and finally 5. In this case, you must select waypoint 3, 1, and 5 in that order when making the route. Add From Map To create a route using the cursor on the map, press the key next to the Add From Map label. A screen similar to the one at right appears. To save the first waypoint location in the route, simply press the arrow keys to move the cursor to the desired location. The latitude/longitude of the cursor shows at the bottom of the screen. When the cursor is at the desired location, press the ENT key. This saves the cursor position as a waypoint. A box appears on the screen with the waypoints number beneath it. Now move the cursor to the next location on the route. As you move the cursor, a line stretches from the first waypoint to the cursor position. When the cursor is at the desired location, press the ENT

The GlobalMap 2000 can display navigation information in magnetic or true. When its turned on for the first time true is used. Press the key next to the Direction label to switch it to magnetic. Speed can show in knots (KN), statute miles per hour (M.P.H.), or kilometers per hour (K.P.H.). The default setting for speed is statute miles per hour. Water depth readings shown on the C-MAP charts and on the sonar can be shown in feet (FT), fathoms (FA), or meters (M). Water temperature readings can show in degrees Fahrenheit (F) or degrees Celsius (C). CONTRAST , VOLUME, and LIGHT ADJUST The display contrast, speaker volume, and light brightness are adjustable from the same menu screen. To adjust any or all of these features, press the MENU key two times, then press the key next to the Contrast, Volume, and Brightness label. The screen shown at right appears. Three vertical bar graphs appear on this screen. When you first enter this screen, the contrast is ready for adjustment. To change another feature on this screen, simply press the left or right arrow key to highlight the desired feature. Then press the up or down arrow keys to increase or decrease the level. When you have everything on this page adjusted as desired, press the CLR key to exit. Note: To turn the lights on, simply press the ON key again after turning the unit on. To turn the lights off, press the ON key again.
MAN OVERBOARD One of boatings most terrifying events is having a friend or family member fall overboard. This situation can be deadly on any body of water, fresh or salt. Its particularly dangerous at night or if youre out of sight of land. Of course, the first thing to do is remain calm and try all standard safety measures to try and rescue the person. If you lose sight of the person, you can use the GlobalMap 2000 to help start a search pattern. Once youre back at the helm after initial rescue efforts have failed, press the MAN OVERBOARD key. A message appears: Now Navigating to Man
Overboard Location. A screen similar to the one at right appears. Your position at the time you pressed the Man Overboard key is shown by a box with the letters MOB inside. All digital navigation displays including Distance (DTG), Bearing (BRG), Course (COG), Speed Over Ground (SOG), and Time To Go (TTG) show data that let you navigate back to the man overboard position. Man Overboard Information Once youve saved a Man Overboard position, the unit shows navigation data to that position until you reset the Man Overboard function, turn the unit off, or use the Cancel Navigation feature. To reset the Man Overboard or view more information about it, press the WAYPT/ROUTE key. Now press the key next to the Man Overboard Information label. The screen shown at right appears. Your position, time, and date when the Man Overboard key was pressed shows at the top of the screen. If you wish to save your present position instead of the one shown at the top of the screen, press the key next to the Save New Man Overboard label. If youre not currently navigating to the Man Overboard position and wish to do so, press the key next to the Navigate to Man Overboard Location label. The GlobalMap 2000 will instantly show navigation data to the position shown at the top of this screen. Once the Man Overboard key is pressed, your present position is saved in memory. Pressing the key again wont save your position again, instead a warning message will appear. This prevents the inadvertent loss of the current Man Overboard position by someone accidentally pressing the Man Overboard key. To reset the Man Overboard function which arms the

key, press the key next to the Reset Man Overboard label on the menu shown above. The GlobalMap 2000 doesnt save the Man Overboard position in the waypoint table. However, it does save the position on the Man Overboard Information screen. To add the position shown at the top of Man Overboard Information menu to the waypoint table, simply press the key next to the Covert Man Overboard to Waypoint label. The unit assigns that position to the first available waypoint number in the waypoint table. This waypoint can be edited the same as any other waypoint on the list, including the name, symbol, and position. Remember, repeated pressing of the Man Overboard key does not repeatedly save your present position! The unit only saves the position the first time the Man Overboard key is pressed. To save a new Man Overboard position, you must first reset Man Overboard by pressing the key next to the Reset Man Overboard label on the Man Overboard Information menu. You can navigate to a waypoint using the Waypoint Recall feature at any time, however this stops the GlobalMap 2000 from navigating to the Man Overboard position. Remember, saving the victim is the primary goal. Try all options to rescue the person immediately after the accident happens. Training and education are also good accident preventative. The Coast Guard has excellent safety courses. Instruct all members on board your boat on safety procedures before leaving the dock. Make certain all on board know what to do before any emergency occurs. DATUMS The GPS navigation system relies on complex mathematical calculations to determine your position based on satellite data and other factors. One factor is the Earths shape. Since the Earth is not a true sphere, variations in the calculations have to be made to accommodate deviations. To make matters more complex, not everyone uses the same data to determine what the deviations are. The size and shape of the ellipsoids that are used to approximate the earths surface are improved often. This can lead to errors if your navigation device uses one ellipsoid, while your chart uses a different one. The term used for these ellipsoids is Datum.
To reduce the error factor between datum, this unit gives you the capability to select the datum used by the unit when displaying the map. You can select a new datum from a list or enter a correction offset based on latitude/ longitude. To change the datum, first press the MENU key three times. Now press the key next to the Datum Translations label. The screen shown below appears. There are two boxes on the left side of the screen. One reads Source Datum, the other is Display Datum. Before changing the Datum, you need to know which datum the navigation receiver supplying position data to the GlobalMap 2000 is using. For example, all Lowrance GPS receivers (including the LGC-1 GPS module) use WGS 84; all Lowrance Loran-C receivers use WGS 72. The display datum box shows the datum currently displayed on the mapping screen by the GlobalMap 2000. If the display datum is different from the source datum, the GlobalMap 2000 translates the source datum to the displayed one. This lets you display a map using any datum on the list on the right side of the screen. To change either the source or displayed datum, first press the key on the right side of the screen next to the desired box that you wish to change. Then press the up or down arrow keys to move highlight the datum you wish to use. For example, to change the source datum from WGS 84 to WGS 72, simply press the key next to the Source Datum label, then press the down arrow key until WGS 72 is highlighted. When the source box shows the correct datum, press the ENT key. This saves the datum displayed in the source box. Once you have the desired datums showing in both the source and the display boxes, press the CLR key. This unit returns to the mapping screen, using the datums you specified. The default for both the source and display datums is WGS 84.

currently in use. Continue pressing the arrow keys until you reach the desired level. If the unit is in the automatic mode, the sensitivity level cant be increased or decreased past a certain point. An easy way to adjust the sensitivity in the manual mode is to first change the range to a depth thats at least twice as deep as the current range. For example, if the range is 0 - 60 feet, change it to 0 - 120 feet. Now increase the sensitivity by pressing the up arrow key until a second bottom signal appears on the screen at twice the depth of the actual depth. This signal is the second echo and is caused by the sound wave travelling from the transducer, striking the bottom, reflecting off the waters surface, and repeating the cycle. Once you see the second echo appear, change the range back to the original scale. The sensitivity level should be close to ideal. If theres too much noise on the screen (random echoes), or if you still cant see enough detail, bump the sensitivity up or down a step. Another way to adjust the sensitivity level is through the menus. Press the MENU key, then press the key adjacent to the Sonar Controls. menu. A screen similar to the one at right appears. Now press the right or left arrow keys to increase or decrease the sensitivity level. The bar graph in the upper left corner of the screen shows the level currently in use. When youre finished with the adjustment, press the CLR key to erase the menus. RANGE The range can only be varied a little when the automatic mode is on. The unit adjusts the range to keep the bottom signal in the lower half of the display at all times. You can change the range to virtually any number between 5 and 5000 feet when the unit is in the manual mode.
To change the range, simply press the up arrow key to decrease it or the down arrow key to increase it. If the unit is in automatic, it may change the range immediately to keep the bottom on the screen. Another way to adjust the range is through the menus. Press the MENU key, then press the key adjacent to the Sonar Controls. menu. A screen similar to the one at right appears. Now press the up or down arrow keys to decrease or increase the range. When youre finished with the adjustment, press the CLR key to erase the menus. The available ranges available with the arrow keys are: 0 - 5, 10, 20, 30, 40, 60, 100, 150, 200, 300, 500, 800, 1000, 1500, 2000, 3000, and 5000 feet; 0 - 3, 5, 10, 12, 15, 20, 30, 40, 60, 100, 150, 200, 300, 400, 600, 1000, and 1500 meters; 0 - 1.2, 2, 5, 7, 10, 15, 20, 30, 40, 60, 80, 100, 150, 200, 300, 500, and 800 fathoms.

UPPER AND LOWER LIMITS When the manual mode is on, the ranges upper and lower limits can be changed in one foot increments provided there is at least ten feet between them. For example, an upper limit of 31 feet and a lower limit of 41 feet has a ten foot range. This feature gives you unparalleled control, allowing you to see virtually any segment of the underwater world. Using the upper and lower limits makes zooming in on structure, fish, and other targets easy. To use the upper and lower limits, first make certain the unit is in the manual mode. Now press the MENU key, then press the key next to the Sonar Controls. label. Finally, press the key next to the More. label at the bottom of the menu. A screen similar to the one at right appears.
To change the upper limit, press the key adjacent to the Upper Limit label. A screen similar to the one at right appears. Using the numbered keys, enter the desired upper limit, then press the ENT key. In this example, we entered 25 feet. The GlobalMap 2000 returns to the sonar menu using the new range as shown below. Changing the lower limit is identical to the upper limit, except you press the key next to the Lower Limit label. Simply enter the desired lower limit and press the ENT key. When youre finished with the upper and lower limits, press the CLR key to erase the sonar menus.
ZOOM Enlarging or zooming the picture is a common method used to show small detail and fish signals. Although changing the upper and lower limits gives you precise control over the range, the zoom feature is faster. The zoom feature works differently in automatic versus manual. Automatic For a fast 2 times view of the current display, simply press the SONAR key. This splits the screen into left and right sides. The right side shows the current information in a normal view. The left side shows all of the echoes from the lower half of the right side at the same time. The left side is actually showing the right sides echoes - but twice as large.
For a full screen zoom view, simply press the SONAR key until the full screen zoom appears. Since the unit is in the automatic mode, the GlobalMap 2000 keeps the bottom signal on the screen at all times, automatically adjusting the range.
Manual If youre in the manual mode, pressing the SONAR key gives you a 2X zoom, identical to the one described above. However, the unit wont track the bottom since its in the manual mode. The bottom signal may drop off the bottom of the screen, or rise above the top. To adjust the zoom while in the manual mode, first press the MENU key, the press the key adjacent to the Sonar Controls. label. Now press the key next to the More. label. A screen similar to the one above appears. Now press the key next to the Adjust Zoom label. The screen shown below appears. Note the zoom bar at the far right side of the screen. All echoes appearing between the top and bottom of this bar are shown on the left side of the screen. If you wish to change this, use the up and down arrow keys to move the zoom bar to the desired location. When youre finished, press the CLR key. An easy way to change the zoom range is to simply press the ZOOM IN or ZOOM OUT keys. These keys work on the sonar screen the same way as they do on the mapping screens.

ASP and Surface Clarity Control Noise, in electronic terms, is any undesired signal. Noise shows on the display as random patterns of dots or lines. In severe cases, it can completely cover the screen with black dots or lines, obscuring target and bottom echoes. Its caused by mechanical and electrical sources such as bilge pumps, engine ignition systems and wiring, air bubbles passing over the transducers face, even engine vibration. This unit has an efficient noise rejection system called Advanced Signal Processing or ASP. Noise signals are effectively reduced or eliminated with this feature. ASP constantly evaluates the effects of boat speed, water conditions, and interference, rejecting signals it recognizes as noise, and letting target and bottom echoes pass. Surface Clarity Control acts only on interference near the surface. This feature reduces the clutter or random signals seen on and near the top of the display. This noise is caused by many things including tiny plant and animal life, wave action, and boat wakes. When the unit is first turned on, or after its reset, both ASP and Surface Clarity Control are automatically enabled. Both features are adjustable or can be turned completely off, if desired. To adjust ASP, press the MENU key, then press the key adjacent to the Sonar Controls label. Now press the key next to the More label until the ASP menu appears as shown at the top of the next page. Youll notice it has two levels: Low and High. To change the ASP level, simply press the key next to the arrow on the ASP menu until the check mark lands on the desired level. When youre finished, press the CLR key. To adjust the Surface Clarity Control, press the MENU key, then press the key adjacent to the Sonar Controls label. Now press the key next to the More label until the Surface Clarity menu appears as shown at the top of the next page. Press the key next to the right arrow in the Surface Clarity menu to increase its level, press the key adjacent to the left arrow to
decrease it. The bar graph and percentage number shows the level of surface clarity in use. Press the CLR key when youre finished. DIGITAL SONAR Each SAM actually has two sonar units in one box. One sonar is dedicated to the graph display, the other is the digital sonar display. The digital sonar is responsible for the digital depth display and the automatic features. If the digital bottom depth display in the upper left corner of the screen flashes, this means the digital sonar has lost the bottom and is trying to reacquire it. The number that it flashes is the last known water depth. You can turn the digital sonar off, if desired. Although you will lose all automatic functions and depth alarms, the chart display will be speeded up slightly. To turn the digital sonar off, press the MENU key, then press the key adjacent to the Sonar Controls label. Now press the key next to the More label until the Digital Sonar menu appears as shown at right. Press the key adjacent to that label. The menu shown below appears. Now press the key adjacent to the Digital Sonar ON OFF label. To turn the digital sonar on again, repeat the above steps. KEEL OFFSET The keel offset feature lets you compensate for the transducers location on the boat. Since this sonar unit measures water depth from the face of the transducer to the bottom, there can be a significant difference between the actual water depth and the depth displayed on the sonar unit. For example, suppose you mount a bolt-thru-hull transducer on the bottom of the hull. When you launch the boat you find that this location places the transducer three feet below the waters surface. Therefore, the depth sounder always reads three feet shallower than the actual water depth. (In other words, if the bottom is 50 feet deep, the depth sounder will read 47

Using LowranceNET NMEA 2000 Devices with LMS-334, LMS-339 & GlobalMap 3600.
The instructions in this document address the operation of a LowranceNET NMEA 2000 network with the LMS-334, LMS-339 and GlobalMap 3600. The following topics are covered in this document. NMEA 2000 Menu On the GPS and Sonar menus (the GlobalMap 3600 only has a GPS menu), the NMEA 2000 entry allows you to configure, calibrate and monitor devices in a LowranceNET NMEA 2000 network. It also provides access to the Buss Setup, Fuel Management and NMEA 2000 Alarm menus. NMEA 2000 alarms are addressed in your unit's manual. Buss Setup From the Buss Setup configuration menu, you can modify the configuration, calibration and advanced option settings of items on the LowranceNET. Internal GPS Receiver The internal GPS receiver in your unit is a non-network device. That means GPS data you receive from the unit will not be transmitted across the network to other network devices. The only way to transmit GPS data across the network is to switch the active antenna setting to read data from an LGC-2000 on the LowranceNET. Fuel Management The Fuel Management menu allows you to maintain and configure fuel flow and fuel consumption.

NMEA 2000 Menu

The NMEA 2000 menu, located on the GPS and Sonar menus in your unit contains three items: Buss Setup, Fuel Management and NMEA 2000 Alarms. NMEA 2000 Alarms are addressed in your unit's manual. To access the NMEA 2000 menu, press MENU, select NMEA 2000 and press ENT.

Calibration

Calibrating Fluid level is an important step to ensuring the status of your tank is correctly transmitted over the NMEA 2000 buss. For example: if you have an odd-shaped tank, like one that is wider at the top than at the bottom, the float inside the tank will tell you there is a half tank of gas when it reaches the midpoint of the tank, regardless of the tanks actual capacity below the midpoint. That could cause you to run out of gas more quickly than expected. Whether the Fluid Type is Fuel, Water, Gray Water, Live Well, Oil or Black Water, calibrating the Fluid Level protects you from unpleasant surprises.

To Calibrate a Device:

From the device configuration menu, press CALIBRATE and press ENT to access the Device Calibration window.

2-Point Calibration

2-Point calibration is best for rectangular or square shaped tanks that allow the fuel level sensor to provide an accurate reading of the fuel level at the top and bottom of the tank. When you select 2-point from the Num Pts menu, the Fluid menu will have two options: Empty Level and Full Level. 1. Highlight NUM PTS, press ENT and select 2. Press ENT.
2. Press to Fluid Level, press ENT, then select the level (EMPTY FULL) that corresponds with your tank's fuel level and press ENT. 3. Press to CALIBRATE and press ENT.

Press to RESTORE DEFAULTS and press ENT, which will launch a confirmation message. To confirm the configuration, press |ENT. 6

Instance

The Instance command is intended for use only by experienced NMEA 2000 network technicians. You should never need this command if you are connecting your unit to a network with similar display units and/or a series of electronic probes. Instance allows network technicians to resolve certain electronic probe conflicts. This is most likely to occur if the network includes LMF-200 or LMF-400 digital gauges, which support the display of fewer electronic probes than your GPS or sonar/GPS unit. If you want to use your unit in a network including one of these digital gauges, you may need to consult customer service.

Internal GPS Receiver

The internal GPS receiver in your unit is a non-network device. That means the GPS data you receive from your unit will not be transmitted across the network to other network devices. The only way to transmit GPS data across the network is to add a LGC-2000 to the LowranceNET.
