Power Connections - All Units This unit works from a twelve-volt battery system. For the best results, attach the power cable directly to the battery. You can attach the power cable to an accessory or power buss, however you may have problems with electrical interference. Therefore, its safer to go ahead and attach the power cable directly to the battery. If the cable is not long enough, splice #18 gauge wire onto it. The power cable has two wires, red and black. Red is the positive lead, black is negative or ground. Make certain to attach the in-line fuse holder to the red lead as close to the power source as possible. For example, if you have to extend the power cable to the battery or power buss, attach one end of the fuse holder directly to the battery or power buss. This will protect both the unit and the power cable in the event of a short. Use a 3-amp fuse. IMPORTANT! Do not use this product without a 3-amp fuse wired into the power cable! Failure to use a 3-amp fuse will void your warranty.

2. Slide the transducer between the two ratchets. Temporally slide the bolt though the transducer assembly and hold it against the transom. Looking at the transducer from the side, check to see if it will adjust so that its face is parallel to the ground. If it does, then the A position is correct for your hull. If the transducers face isnt parallel with the ground, remove the transducer and ratchets from the bracket. Place the ratchets into the holes in the bracket with the letter B aligned with the dot stamped in the bracket. Reassemble the transducer and bracket and place them against the transom. Again, check to see if you can move the transducer so its parallel with the ground. If it does, then go to step 3. If it doesnt, repeat step 2, but use a different letter until you can place the transducer on the transom correctly.

RATCHETS

3. Once you determine the correct position for the ratchets, assemble the transducer as shown below. Dont tighten the lock nut at this time.

METAL WASHER

RUBBER WASHERS BOLT
4. Hold the transducer and bracket assembly against the transom. The transducer should be roughly parallel to the ground. The bottom of the transducer bracket should be in line with the bottom of the hull. Dont let the bracket extend below the hull! Mark the center of the slots for the mounting holes. Drill two 5/32" holes in the marked locations for the #10 screws supplied with the transducer.

TRANSOM

SIDE VIEW
5. Attach the transducer to the transom. Slide the transducer up or down until its aligned properly on the transom as shown above. Tighten the brackets mounting screws. Adjust the transducer so that its parallel to the ground and tighten the lock nut until it touches the flat washer, then add 1/4 turn. Dont over tighten the lock nut! If you do, the transducer wont kick-up if it strikes an object in the water.
6. Route the transducer cable to the sonar unit. If possible, route the transducer cable away from other wiring on the boat. Electrical noise from the engines wiring, bilge pumps, VHF radio wires and cables, and aerators can be picked up by the sonar. Use caution when routing the transducer cable around these wires. IMPORTANT! Clamp the transducer cable to the transom close to the transducer. This can prevent the transducer from entering the boat if it is knocked off at high speed. 7. Make a test run to determine the results. If the bottom is lost at high speed, or if noise appears on the display, try sliding the transducer bracket down. This puts the transducer deeper into the water, hopefully below the turbulence causing the noise. Dont allow the transducer bracket to go below the bottom of the hull! Periodically wash the transducers face with soap and water to remove any oil film that may collect. Oil and dirt on the face will reduce the sensitivity or may even prevent operation.

FINDING YOUR POSITION

Auto Search To lock onto the satellites, the GPS receiver needs to know its current position, UTC time, and date. (Elevation (altitude) is also used in the equation, but its rarely required to determine a position.) It needs this data so that it can calculate which satellites should be in view. It then searches for only those satellites. When your GPS receiver is turned on for the first time, it doesnt know what your position or elevation (altitude) is. It does know the current UTC time and date since these were programmed into it at the factory and an internal clock keeps the time while the unit is turned off. It begins searching for the satellites using the above data that it acquired the last time it was turned on. This probably was at the factory. Since its almost certain that youre not at our factory, its probably looking for the wrong satellites. If it doesnt find the satellites its looking for after five minutes, it switches to Auto Search. The receiver looks for any satellite in the sky. Due to advanced technology, the auto search time has shrunk to about five minutes, so the longest time you should ever have to wait is ten minutes from the time you turn the unit on until it locks onto the satellites and shows a position. Once the unit locks onto the satellites, it should take less than a minute to find your position the next time its turned on, provided you havent moved more than approximately 100 miles from the last location it was used. Manual Initialization If you dont want to wait for the Auto Search, then you may be able to speed up the initialization process by using the manual initialization feature. Using this feature tells the unit its approximate position. Once it knows its location, it determines exactly which satellites should be in view and starts looking only for those satellites. To manually initialize the unit, press the MENU key. Now press the down arrow key until the GPS SETUP label is highlighted. Press the right arrow key. The INITIALIZE GPS label is highlighted. Press the right arrow key again. A screen similar to the one at right appears. Use the arrow keys to move the crosshairs to your approximate location on the map. You can use the ZIN and ZOUT keys to enlarge the map which makes it easier and faster to find your location. The box at the top of the screen shows the latitude and longitude of the cursor position, along with the distance and bearing from the last known position. Once you have the crosshairs on your location, press the ENT key. The unit returns to the satellite status screen.
Using the manual initialization method loads a position thats close to yours into the GPS receiver. It should now have position, time, and date, thereby giving it the data it needs to determine which satellites are in view. Once the satellites are known, the receiver searches for only those satellites, making a lock faster than an auto search method. All position and navigation data flashes until the unit acquires a position. Do not rely on any data that is flashing! When the numbers are flashing, they represent the last known values when the unit lost its lock on the satellites. Position Aquisition When the receiver locks onto the satellites and calculates a position, it shows the message Position Acquired on the screen. Once the unit has acquired the satellites and the position acquired message appears, its ready for use. (Note: The altitude data may still flash even if the unit shows a Position Acquired message and all other data is not flashing. The unit must be locked onto at least four satellites to determine altitude. It only takes three satellites to determine position. You can navigate with this unit if the altitude is flashing, simply ignore the altitude display until it quits flashing.) REMEMBER, DO NOT NAVIGATE WITH THIS UNIT UNTIL THE NUMBERS STOP FLASHING! MODES The LMS-160 has five modes: status, navigation, sonar, map, and window groups. The GlobalMap 1600 has four - no sonar mode. Use the PAGES and arrow keys to switch between the different screens. The four GPS screens that show by default are shown at the top of the next page. (See the sonar section in this manual for information on sonar operation.) To change modes, simply press the PAGES key. A screen similar to the one at right appears. Use the up or down arrow keys to change modes. (The windows mode is shown as groups. Group A is the first windows group.) Press the right arrow key while the above menu is showing to switch between different versions of each mode. When the desired screen appears, press the EXIT key to erase the menu.

STATUS

NAVIGATION
SONAR (GLOBALMAP 1600 ONLY)

MAPPING

WINDOW GROUPS
Navigation There are two different navigation screens. Nav screen number one shows a graphical view of your trip, Nav screen number 2 shows all navigation details in large digital numbers. You can also customize both navigation screens to show data other than the default. See the Programming Boxes section for more information. Nav-1 This screen has a compass rose that shows not only your direction of travel, but also the direction to a recalled waypoint. The navigation screen looks like the one at right when youre not navigating to a waypoint. Your position is shown by an arrow in the center of the screen. Your trail history, or path youve taken is depicted by the line extending from the arrow. The arrow pointing down at the top of the compass rose indicates the current track (direction of travel) you are taking. This is also shown in the TRK (track) box in the upper right corner of the screen. On the example shown at right, the track is 240. The current ground speed (GS) shows in the box in the lower center of this screen. When navigating to a waypoint, Nav screen number one looks like the one at the top of the next page. Bearing to the destination waypoint is in the box in the upper left corner. Bearing is also shown by the large arrow
pointing up towards the compass, above the present position arrow. Distance from the present position to the waypoint (DIS) shows beneath the compass on the lower left side of the screen. Next to the distance box is estimated time enroute (ETE). This is the estimated time that it will take you to arrive at the destination, based upon current track and ground speed. In the lower right corner is the course (CRS) box showing the direction from your starting position to the waypoint. Remember, a course is a proposed path from the starting position to the destination. Track is your actual direction of travel. Lines on either side of the present position show the current cross track error range. Cross track error is the distance you are off-course to the side of the desired course line. The course line is an imaginary line drawn from your position when you started navigating to the destination waypoint. Its shown on the screen as a vertical dotted line. The default for the cross track error range is 0.20 mile. For example, if the present position symbol touches the right cross track error line, then you are.25 mile to the right of the desired course. You need to steer left to return to the desired course. You can use the ZIN or ZOUT keys to change the cross track error range. A circle depicting your destination (waypoint) appears on the screen as you approach the waypoint as shown on the screen at right. Nav-2 This navigation screen shows all navigation information in large digital numbers. To view this screen, press the PAGES key, then press the up arrow key until the NAV 1 label is highlighted. While its highlighted, press the right arrow key. The screen shown at right appears. Press the EXIT key to erase the menu. This screen is composed of eight digital boxes. Track (TRK) and ground speed (GS) data are the only ones that show data if youre not navigating to a waypoint. If you are navigating to a waypoint, then bearing (BRG), distance to waypoint (DIS), estimated time en route (ETE), cross track error (XTK), estimated time of arrival (ETA), and the CDI also operate.

from your present position. The zoom-in and zoom-out keys work from the cursors position when its active - not the present position. You can zoom in on any detail, anywhere. The cursor can also place icons and waypoints. When the cursor is used with map-1, its position, bearing, and distance from your present position show at the top of the screen. Cursor Distance You can use the cursor to find the distance between two points. While the cursor is showing, press the MENU key, then select "FIND DISTANCE". The unit returns to the mapping screen. Now move the cursor to the first location that you want to measure the distance from and press the ENT key. Now move the cursor to the position that you want to measure the distance to. A line is drawn from the point when the ENT key was pressed to the cursor's present location. The distance covered by the line shows at the top of the screen. To measure another two points, simply move the cursor and press the ENT key. Press the EXIT key to erase the cursor. The unit centers your present position on the screen after erasing the cursor.
MAP SETUP The map has many customization options. To change them, first press the MENU key while a map is showing on the screen. The map setup label is highlighted. Press the right arrow key. A screen similar to the one at right appears. Change Maps Changes made to the map using the options in the Map Setup is normally made to all map screens. The change can be limited to the map screen currently in use, however, by switching the All Maps to This Map in the Change menu. To do this, simply highlight the Change label, then press the right arrow key. To switch back, repeat the above.
Map Options The following map options are listed under the Map Options menu: Map Orientation, Auto Zoom, Range Rings, and Latitude/Longitude Grids. Map Orientation By default, this receiver shows the map 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. What you see to your left corresponds to the left side of the map, to your right is shown on the right side of the map, and so on. However, if you travel any other direction, the map doesnt line up with your view of the world. To correct this problem, a track-up mode rotates the map as you turn. Thus, what you see on the left side of the screen should always be to your left, and so on. A course-up mode keeps the map at the same orientation as the initial bearing to the waypoint.

NORTH-UP

TRACK-UP

COURSE-UP

In the north-up view shown at left, were travelling east. In this view, the present position indicator appears to move towards the right side of the screen. In the track-up view, the present position moves straight towards the top of the display. 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, the screen is locked into your original bearing to the recalled waypoint, regardless of your track. To select the desired mode, first press the MENU key, select MAP 1 SETUP, then select MAP OPTIONS. Finally, select ORIENTATION and press the right or left arrow key until the desired mode appears. Press the EXIT key to erase this menu.

tance from the first waypoint in the route to the second showing under the second waypoints name.
Add From Map You can add waypoints from the map, even create new ones. To do this, select ADD FROM MAP from the menu as shown on the previous page. A screen similar to the one at right appears. Using the arrow keys, move the cursor to the desired waypoint or location. Now press the ENT key to add it to the route. If its an existing waypoint, it will be added to the route. If you mark a location with the cursor that isnt a waypoint, the unit will create a waypoint and add it to the route. To add another location or waypoint to the route, move the cursor to that location and press the ENT key. When youre finished, press the EXIT key. The screen below right appears. The total route distance shows at the bottom of the screen. Continue selecting waypoints until all of the waypoints in the route are on the list. Press the EXIT key to return to the Route menu. Your route is now saved in memory. Press the EXIT key to erase the menus. Delete a Waypoint from the Route To remove a waypoint from a route, first select the route, then select the waypoint that you want to delete and press the right arrow key. 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 simply removes it from the route.) Waypoint Statistics By default, this unit shows the distance and bearing from each waypoint in the route to the next. It will also show estimated time en route (ETE), estimated time of arrival (ETA), or the waypoint names (NAMES). To view the different statistics, highlight the SHOW INFO-DIS/BRG label, then press the left or right arrow key until the desired statistic appears.
Follow a Route - Direct To Method Before starting the route, youll need to decide if you want to start at the first waypoint and travel forward to the last waypoint or start at the last waypoint in the route and travel backwards (reverse) to the first waypoint. The default is forward. You can also start at the closest waypoint to your position, then travel forward or reverse through the route using the AUTO START feature. To follow a route, first select the route number that you wish to follow by highlighting the Route # label, and pressing the left or right arrow keys until the desired route number appears. In this example were using route number one. To run the route from the last waypoint to the first, highlight the RUN ROUTE label and press the right arrow key to change it from forward to reverse. Now highlight the first waypoint in the route that you wish to start with and press the right arrow key. (The first waypoint in the route is used in this example.) The screen shown above right appears. Now select DIRECT TO and press the right arrow key. The unit returns to the last used navigation, mapping, or windows screen. In this example, map screen 1 was in use. A box with the S inside represents your location when you started the route. A dotted line shows from your starting position to the waypoint. A dashed line extends from this waypoint to each of the other waypoints in the route. Follow these lines to get to each of the waypoints. When you enter the radius set by the arrival alarm, the unit 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.) The unit continues to show navigation data to the last waypoint in the route until you end the navigation. (See Cancel Navigation) Following a Route - Auto Start Method You dont have to choose the starting waypoint in a route. Selecting AUTO START on the route planning menu, starts navigation along the leg of the route that is closest to your present position. The screen shown at the top of the next page shows the result of the auto start feature. When the route was started, the first leg of the route (from waypoint #3 to waypoint #4)

Change Units You can view data in three different formats: statute, nautical, and metric. The default is statute. The chart below shows the settings for each. Statute Nautical Distance.. miles. nautical miles. Speed. miles per hour. knots.. Altitude. feet. feet.. Metric kilometers kilometers per hour meters
The unit will also show bearing in degrees true or magnetic, water depth in feet, fathoms, or meters, temperature in degrees Fahrenheit or Celsius, (temperature requires an optional temp sensor) and the clock in 12 hour (a.m./p.m.) or 24 hour formats. To change a unit of measure, first select Change Units from the System Setup menu. 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 This product transmits data through the power/data port in the back of the unit using NMEA 0183 format, version 1.5 or 2.0. The 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. See the installation section for cable connections. See the sample wiring diagram below for general wiring procedures. Read your other products owners manual for more wiring information.

Once the cables are wired, turn the unit on, press the menu key, and select NMEA / DGPS CONFIG from the System Setup menu. A screen similar to the one at right appears. To turn the NMEA output on, highlight the NMEA OUT menu (shown at right), 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 this unit and the wiring is correct, then you may need to change the NMEA or the serial communication settings. Configure NMEA Highlight the Configure NMEA menu, then press the right arrow key. The screen shown at right appears. NMEA 0183 Version There are two versions of the NMEA data, 1.5 and 2.0. If your other equipment requires 1.5, press the left arrow key to select it. GLL, RMC/RMB, APB, GGA, GSA/GSV Sentences Some equipment requires different sentence. The 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 This unit will recognize Starlink and Magnavox automatic DGPS receivers. If you have either one of these receivers, simply highlight the STARLINK DGPS or MAGNAVOX DGPS on the NMEA / DGPS menu (shown at the top of this page) and press the right arrow key to turn it on. (Note: If you have a Magnavox DGPS receiver connected, this unit 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 this unit, 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 the top of the next page appears.

SIMULATOR A simulator is built into this unit that moves the GPS position and produces a simulated sonar chart. You can use nearly all of the units features - even save and recall waypoints. This is useful for trip planning. To use the simulator, press the MENU key, then press the up or down arrow keys until the Simulator Setup menu is surrounded by the black box. Now press the right arrow key. The screen shown at right appears. If you simply press the right arrow key, turning the simulator on, this unit will start from your present position and follow a track of 355 at 100 miles per hour. To change either the track or speed, highlight the one you want to change, then press the right or left arrow key. When the numbers are correct, press the EXIT key. Starting Position Normally, the starting position for the simulator is your present position. If you want to change the starting position, highlight the SET START WPT label on the Simulator Setup menu, then press the right arrow key. You can select any waypoint as the simulators starting point. Select the starting point by pressing the right arrow key on the WPT# label until the desired starting waypoint number appears. Now highlight the SET SIM START label and press the right arrow key. The unit returns to the Simulator Setup menu using the specified waypoint as the starting waypoint. Steer Simulator This option lets you change both the course and speed on the screen as the simulator is running. To do this, highlight the STEER SIMULATOR label on the Simulator Setup screen, then press the right arrow key. The screen shown at right appears. Use the up and down arrow keys to increase or decrease the speed. Use the right and left arrow keys to change the track. When youre finished changing the track and speed, press the EXIT key to erase the menus.
SONAR OPERATION - LMS-160 ONLY
SONAR MODES The LMS-160 has three different sonar modes: full chart (sonar 1), split-chart (sonar 2), and sonar with digital information (sonar 3). To select a mode, first press the PAGES key. Press the up or down arrow key to select sonar modes, then press the left or right arrow key to select the desired mode. Press the EXIT key to erase the modes menu. Full Chart This is the default mode used when the unit is first turned on (shown above). The bottom signal scrolls across the screen from right to left. Depth scales on the right side of the screen makes it easy to determine the depth of fish, structure, and other objects. The line at the top of the screen represents the surface. The bottom depth shows at the top left corner of the screen. The word AUTO at the screens top center shows that its in the automatic mode, freeing you from sensitivity, range, and noise rejection adjustments. Split Chart A split chart shows the underwater world from the surface to the bottom on the right side of the screen. The left side shows an enlarged version of the right side. The zoom range shows at the bottom of the screen. In this example, the zoom range is 2X, or two times the right sides view.

The Surface Clarity Control (SCC) reduces or eliminates surface clutter signals from the display. SCC varies the sensitivity of the receiver, decreasing it near the surface and gradually increasing it as the depth increases. There are three levels of SCC available on this unit: low, medium, and high. When its turned on for the first time, the SCC level is low. To change it, press the MENU key, then select SONAR OPTIONS. The screen at righ appears. Use the up or down arrow keys to select the SURFACE CLARITY menu. Now use the left or right arrow keys to change it. When youre finished, press the EXIT key to erase the menus. ASP (Advanced Signal Processing) The ASP feature is a noise rejection system that constantly evaluates the effects of boat speed, water conditions, and interference. This automatic feature gives you the best display possible under most conditions. The ASP feature is an effective tool in combating noise. In sonar terms, noise is any undesired signal. It is caused by electrical and mechanical sources such as bilge pumps, engine ignition systems and wiring, air bubbles passing over the face of the transducer, even vibration from the engine. In all cases, noise can produce unwanted marks on the display. The ASP feature has two levels - Normal and High. If you have high noise levels, try using the High ASP setting. However, if you are having trouble with noise, we suggest that you take steps to find the interference source and fix it, rather than continually using the unit with the high ASP setting. However, there are times when you may want to turn the ASP feature off. This lets you view all incoming echoes before they are processed by the ASP feature. To change the ASP level, press the MENU key. select "SONAR SETUP", then SONAR OPTIONS, and finally press the up or down arrow keys until the ASP menu appears, as shown at the top of this page. Now use the left or right arrow keys to change it. When youre finished, press the EXIT key to erase the menu. RANGE - Automatic When turned on for the first time, the bottom signal is automatically placed in the lower half of the screen. This is called Auto Ranging and is part of the automatic function. Typically, the range cannot be changed manually
while the unit is in automatic, as shown at right. However, depending upon the bottom depth and the current range, you can change the range to a different depth. In the example screen shown at right, the bottom depth has descended to a point where you can change the range to XX feet. To do this, select CHART RANGE from the SONAR OPTIONS menu. Simply press the right or left arrow keys to select a different range. When youre finished , press the EXIT key to erase the menu. RANGE - Manual You have complete control over the range when the unit is in the manual mode. To change the range, first make certain the unit is in the manual mode. Next, select CHART RANGE from the "SONAR OPTIONS" menu. Simply press the right or left arrow keys to select a different range. Press the left or right arrow keys to decrease or increase the range. The available ranges are 0-10, 20, 30, 40, 60, 100, 150, 200, 300, 500, 800, and 1000 feet. After selecting the range, press the EXIT key to erase the range menu. NOTE: The sonars depth capability depends on the transducer installation, water and bottom conditions, and other factors. CHART OPTIONS Chart Speed The rate echoes scroll across the screen is called the chart speed. Its adjustable by selecting CHART SPEED from the "CHART OPTIONS" menu. Increase the chart speed by pressing the right arrow key or decrease it by pressing the left arrow key. The percentage of chart speed in use changes as the arrow keys are pressed.

CHART DISPLAY The chart display lets you set up the screen to show the digital displays, such as depth, temperature, and water speed. You can also turn the zoom bar and zone alarm bars on or off. To make these changes, press the MENU key and select SONAR SETUP, then select CHART DISPLAY. The screen shown at right appears. The digital depth display at the top left corner of the screen normally shows in large numbers. You can change this to smaller numbers or turn it off completely by selecting DIGITAL DEPTH at the top of the screen. Use the up or down arrow keys to select an item, then use the left or right arrow keys to change it. Press the EXIT key to erase this menu. Zoom Bar The zoom bar shows the section of water on the right side of SONAR-2 that is being enlarged on the left side. To turn the zoom bar on continuously, select ZOOM BAR on the CHART DISPLAY menu, then press the right arrow key. Now press the EXIT key. A screen similar to the one at right appears. Press the up arrow key to move the zoom bar up or the down arrow key to move it down. This moves the zoom coverage area. To turn the zoom bar off, repeat the above steps.
Zone Alarm Bar The zone alarm has a range bar. Any echoes that appear between the top and bottom of this bar triggers the zone alarm. This bar normally doesnt show on the screen. To turn the zone bar on continuously, select ZONE BAR from the CHART DISPLAY menu, then press the right arrow key. Now press the EXIT key. A screen similar to the one at right appears. To turn the zone bar off, repeat the above steps. See the Alarms section for more information on the zone alarm. CHART CURSOR This unit has a chart cursor that allows you to pinpoint a targets depth. The cursor is simply a horizontal line that extends across the display from left to right. A depth box at the end of the line on the right side shows the lines depth. In the example at right, the cursor (line) is at 41.1 feet. To display the chart cursor, press the MENU key and select SONAR SETUP, then select USE DEPTH CURSOR. A screen similar to the one at right appears. Use the up and down arrow keys to move the cursor up or down to the desired depth. To turn the chart cursor off, simply press the EXIT key. DIGITAL SONAR Normally, the digital depth display is located at the top left corner of the screen. This display comes from a separate digital sonar built into the unit. It displays only the bottom depth. If it loses the bottom, the last known depth will flash on the display. When the digital finds the bottom, it will automatically display the bottom depth again. The digital sonar can be turned off, however this also turns all automatic features off also, such as auto sensitivity, auto ranging, and the Fish ID. feature. To turn the digital off, first press the MENU key and select SONAR SETUP, then select DIGITAL SONAR. Press the left arrow to turn it off. CAUTION! Turning the digital sonar off also turns the automatic mode off, including Fish ID, and the depth alarms.

by highlighting the Shallow Alm label and pressing the right arrow key. With the shallow alarm set at ten feet, anytime the digital display goes below ten feet, the shallow alarm sounds. Set the deep alarm in the same manner. If the bottom depth reading goes below the deep alarm setting, the deep alarm will sound. ZONE ALARM The zone alarm is triggered when any echo passes inside the zone alarm bar, shown on the right side of the screen. To turn the zone alarm on, highlight the Zone Alarm label on the sonar alarm menu, then press the right arrow key. To adjust the zone alarm, highlight the Adjust Zone label, then press the right arrow key. A screen similar to the one at right appears. To adjust the top of the zone bar higher or lower, press the up or down arrow keys while the START label is highlighted as shown on the screen at right. To adjust the bottom of the zone bar, first press the right arrow key to select END on the screen, then use the up or down arrow keys. When the zone alarm is set, press the EXIT key to erase the menus. FISH ALARM Use the fish alarm for a distinctive audible alarm when fish or other suspended objects are detected by the Fish I.D. feature. A different tone sounds for each fish symbol size shown on the display. To turn the fish alarm on, select FISH ALARM from the sonar alarm menu and press the right arrow key. The unit will revert to the sonar display with the fish alarm turned on. Repeat the above steps to turn the fish alarm off. Note: If the unit is in the manual mode, turning the Fish Alarm on will also turn the automatic mode and Fish ID on, also. Keel Offset Normally, this unit measures water depth from the face of the transducer. Since the transducer is below the surface of the water, this distance is not the exact water depth. If the transducer is one foot below the surface, and the screen shows the water depth as 30 feet, then the depth is actually 31 feet. You can calibrate the depth reading using the keel offset feature. First,
highlight the SET KEEL OFFSET label on the System Setup menu, then press the right arrow key. The screen shown at right appears. The current bottom depth shows in the upper left corner of the screen. The keel offset shows beneath it. In this example, we need to change the keel offset so that the unit will add one foot to the depth, since the transducer is one foot below the surface. Press the right arrow key, then the up or down arrow keys until +1.0 appears in the box, as shown at right, then press the ENT key. This immediately changes the digital depth display at the top of the screen by one foot. Press the EXIT key to erase this menu. Note: Another way to use the keel offset feature is if you want to know the depth of the water below the lowest part of the boat, instead of the surface. To do this, measure the lowest part of the boat below the transducer. In this example, well use 3 feet. Now, using the keel offset feature, adjust the offset for a negative 3 feet. Please note that adjusting the keel offset only affects the digital depth display and all features that use the digital depth, such as the depth alarms and FishTrack. This doesnt affect the chart at all. Calibrate Speed You can calibrate the speed display if an optional speed sensor is attached. To do this, highlight the Calibrate Speed label on the System Setup menu, then press the right arrow key. A screen similar to the one at right appears. If the digital speed display is slower than your actual speed, add a positive percentage to make it read faster. If the digital speed display is faster, use a negative percentage to make it read slower. Use the arrow keys to change the speed, then press the ENT key. Press the EXIT key to erase this menu.

To unit LGC-2000

25' Y-adapter extension cable To NMEA 2000 network port LGC-2000 and GPS unit connection to NMEA 2000 buss.
You can also attach the antenna to a remote port on the network, and pass position information along the network. To do this, simply attach the LGC-2000's connector to one end of the buss adapter cable and attach the other to an available port on the NMEA 2000 buss, as shown in the following image. (You will have to use a similar adapter cable to connect the GPS unit to the NMEA buss as described later in this section.)
To NMEA 2000 network port LGC-2000
LGC-2000 remote connection to NMEA 2000 buss.
NOTE: An existing operational NMEA 2000 buss will already have terminators in place and will already be powered. If you're connecting to such a network, you won't need the terminators or extension cable provided. Do not add terminators or power to a functional NMEA 2000 buss! When the LGC-2000 is connected to the unit (directly or indirectly), it will begin providing GPS signal information.

Power Connections

Your unit comes with a power/data cable that splits into three ends, each with several exposed wires (shown in the following figure). The end with 4 wires (blue, yellow, orange and shield) is a Data cable that connects to a NMEA 0183 interface. The end with three wires (red, black and shield) is a power cable that connects to a NMEA 2000 buss. The thicker three-wire cable (red, black and white) is the Power Supply for your unit (and optional external speaker connection for some units).
Power Supply wires: red, black and white To unit NMEA 2000 Power wires: red, black and shield Data Cable wires: blue, yellow, orange and shield The Power/Data cable for this unit.
Depending on your configuration, you may not use all of these wires. The following segments include instructions for installing all the wires that you will use with this unit. Caution All of the wires in the power/data cable have bare ends for easier installation. The bare ends on any unused wires could cause an electrical short if left exposed. To prevent this, you should cover the individual wire ends either by capping them with wire nuts or wrapping them with electrical tape. (You should cut off the bare wire before taping off the ends.) 32

Powering a NMEA 2000 Buss
(NMEA 2000 Power cable) A NMEA 2000 buss must be connected to a power source to operate. If you have a pre-existing NMEA 2000 installation, it may already be connected to another power source. If your NMEA 2000 buss is already powered, you can ignore the NMEA 2000 Power cable. Never attach two power sources to a single NMEA 2000 buss. If you do need to power your NMEA 2000 buss, attach the NMEA 2000 Power cable to your boat's battery just as indicated in the following segment for connecting your unit's Power Supply cable. The NMEA 2000 Power cable's red wire should be attached (with provided 3-amp fuse) to the boat battery's positive terminal, and the NMEA 2000 Power cable's black and shield wires should both be attached to the battery's negative terminal. NOTE: If the NMEA 2000 buss draws power directly from the boat's battery, the LGC-2000 will remain on (drawing power) all the time. The LGC2000's current draw is very small and shouldn't decrease the boat's storage battery life, but if this small draw is a concern, you can install a switch between the NMEA 2000 buss and the battery. Powering Your Unit (Power Supply cable red and black wires) The unit works from a 12-volt battery system. For the best results, attach the power cable directly to the battery. You can attach the power cable to an accessory or power buss, however you may have problems with electrical interference. Therefore, it's safer to go ahead and attach the power cable directly to the battery. CAUTION: When using the unit in a saltwater environment, we strongly recommend that you shut off the power supply to the power cable when the unit is not in use. When the unit is turned off but still connected to a power supply, electrolysis can occur in the power cable plug. This may result in corrosion of the plug body along with the electrical contacts in the cable and the unit's power socket. In saltwater environments we recommend you connect the power cable to the auxiliary power switch included in most boat designs. If that results in electrical interference, or if such a switch is not available, we recommend connecting direct to the battery and installing an inline switch. This will let you shut off power to the 33

Alarms

This unit has three different types of sonar alarms. The first is the Fish Alarm. It sounds when the Fish I.D. feature determines that an echo is a fish. Another alarm is the Zone Alarm, which consists of a bar on the side of the screen. Any echo on the chart that appears inside this bar triggers this alarm. The last alarm is the Depth Alarm, which has both a Shallow and a Deep setting. Only the bottom signal will trigger this alarm. This is useful as an anchor watch, a shallow water alert or for navigation. Depth Alarms The depth alarms sound a tone when the bottom signal goes shallower than the shallow alarm's setting or deeper than the deep alarm's setting. For example, if you set the shallow alarm to 10 feet, the alarm will sound a tone if the bottom signal is less than 10 feet. It will continue to sound until the bottom goes deeper than 10 feet. The deep alarm works just the opposite. It sounds a warning tone if the bottom depth goes deeper than the alarm's setting. Both depth alarms work only off the digital bottom depth signals. No other targets will trip these alarms. These alarms can be used at the same time or individually.

FishTrack

The FishTrack feature shows the depth of a fish symbol when it appears on the display. This lets you accurately gauge the depth of targets. This feature is available only when the Fish I.D. feature is on. The default setting for FishTrack is off. To turn on FishTrack: (Note: These instructions will turn on FishTrack and Fish I.D. at the same time.) 1. From the Sonar Page, press MENU| to SONAR FEATURES|ENT. 2. Press |then press to FISH DEPTHS|ENT|EXIT|EXIT. To turn off FishTrack, repeat the instructions in step 1. Turning off FishTrack in this manner will not turn off Fish I.D. symbols.

Frequency (Change Transducer Frequency) (LMS-337CDF only)
The LMS-337CDF transducer can operate at both 200 kHz and 50 kHz. The 200 kHz frequency has a 12 cone angle and the 50 kHz frequency has a 35 cone angle. The default frequency is 200 kHz, which is best for use in shallow water (about 300 feet or less). This frequency is the best choice for about 80 74
percent of the fresh and salt water sport fishing applications. When you get into very deep salt water, 300 to 500 feet or deeper, the 50 kHz frequency is the best choice. The 200 kHz transducer will give you better detail and definition, but less depth penetration. The 50 kHz transducer will give you greater depth penetration, but a little less detail and less definition. (Remember, all sonar units typically read deeper in fresh water than in salt water.) There is a common exception to these rules of thumb. Some fishermen on freshwater lakes (or the ocean) using downriggers like to see them on the sonar. In many of those cases, you'll see a 50 kHz transducer frequency in use because the wider cone angle lets them watch the bait.

The Navigation Page has its own menu, which is used for some advanced functions and for setting various options. (Options and setup are discussed in Sec. 8). To access the Navigation Page Menu, from the Navigation Page, press MENU. Map Page The Map Page screens show your course and track from a bird's-eye view. By default, this unit shows the map with north always at the top of the screen. (This can be changed. See the topic Map Orientation, in Sec. 8.) If you're navigating to a waypoint, the map also shows your starting location, present position, course line and destination. You, however, don't have to navigate to a waypoint to use the map. Map Page is the default screen that appears when you turn on the unit. To get to the Map Page from another page: Press PAGES| or to MAP|EXIT. When the Map Page is displayed, a screen similar to the following figures appears. The arrow in the center of the screen is your present position. It points in the direction you're traveling. The solid line extending from the back of the arrow is your plot trail, or path you've taken. The map zoom range is the distance across the screen. This number shows in the lower right corner of the screen. In the first of the following example figures, the range is 4,000 miles from the left edge of the map to the right edge of the map. The Zoom In and Zoom Out keys zoom the map to enlarge or reduce its coverage area and the amount of mapping detail shown. There are 39 available map zoom ranges, from 0.02 miles to 4,000 miles.
Left, Map Page opening screen. Center, zoomed to 100 miles and right, zoomed to 10 miles. Over Zoomed means you have reached the detail limits in an area covered only by the basic background map. Zooming in any closer will reveal no more map details because a high-detail custom map has not been loaded on the MMC for this area.
If you're using only the factory-loaded background map, the maximum zoom range for showing additional map detail is 20 miles. You can continue to zoom in closer, but the map will simply be enlarged without revealing more map content (except for a few major city streets.) Load your own high-detail custom map made with MapCreate (or a pre-made FreedomMap from LEI), and you can zoom in to 0.02 miles with massive amounts of accurate map detail.

Transfer Custom Maps and GPS Data Files
Custom Maps: Custom maps work only from the MMC card or SD card. When a card containing a Custom Map File is loaded into the unit, the unit automatically loads the map into memory when the unit is turned on. Instructions for copying Custom Map Files to an MMC are contained in the instruction manual for your MMC card reader and MapCreate 6 software. For instructions on inserting an MMC into the unit, see Sec. 2, Installation/Accessories. NOTE: To load a Navionics chart, see Sec. 8 for the entry Navionics Charts. GPS Data files: GPS Data Files contain waypoints, routes, trails and event marker icons. Instructions for copying GPS Data Files between your computer and an MMC are contained in the instruction manual for your MMC card reader and MapCreate 6 software. GPS data automatically recorded in the unit's internal memory must be saved to the MMC (as a GPS Data File) in order to store it on your personal computer. GPS Data Files stored on an MMC must be copied from the card to the unit's internal memory before the unit can read them. Here's how: 1. Insert the MMC into your unit. Press MENU|MENU| to SYSTEM SETUP|ENT| to TRANSFER MY DATA|ENT and the screen below appears.
The Transfer My Data submenu asks if you want to save data to the MMC or load data from the MMC into the unit's memory.
2. The Transfer My Data menu includes a message which tells you if an MMC is present or not. If no MMC is present, you must first insert a card into the unit in order to activate the Load or Save commands. To transfer data from the unit to the MMC: press ENT (for SAVE.) To transfer data from the MMC to the unit: press to LOAD|ENT. 3. Saving to MMC: To accept the default name "Data" for the GPS Data File, press to SAVE DATA|ENT. If you wish to rename the file (as shown in the following figures), press ENT to activate the selection box. Press or to change the first character, then press to the next character and repeat until the name is correct. Then, press ENT| to SAVE DATA|ENT. The unit will display first a progress message followed by a completion message when the data transfer is finished. To return to the Page view, repeatedly press EXIT.
From left to right, these figures show the menu sequence for naming and saving a GPS Data File from the unit's memory to an MMC.
