Free Training Aids Available
Now that you know something about the technology that makes this unit possible, you are ready to start learning how to use that technology. This manual will guide you through the process of setting up and running your unit, but that is only one of many resources available. If you or a friend has Internet access, visit our web site. Find us at WWW.LOWRANCE.COM. The site is packed with additional information on using our products. For instance, you can learn more about interpreting what you see on your sonar screen with our free Sonar Tutorial. The tutorial includes animated illustrations and more pictures of actual sonar returns, all described in detail. There's even a printer friendly version of the tutorial available on our web. It makes a great supplement to this manual.
Sonar Viewer You can also download a free copy of our Sonar Viewer software. This PC-based software application plays back any sonar chart log recorded with a Lowrance sonar product. Features include: Adjustable range, zoom, sensitivity, ColorLine, noise rejection, surface clarity, etc. Color interpretation of sonar signals can be user defined. Operates like a Windows Multimedia Player with forward, reverse, pause, fast forward, fast reverse, and scroll buttons. Adjustments update the entire record displayed. Can print in full color. Window can dynamically be sized on your monitor. Mouse cursor shows GPS position, depth and sounding number anywhere on the visible record.
Emulator For the ultimate training aid, be sure to download the free emulator software for your unit. This program can help you learn both basic and advanced operations without burning boat fuel! This PC application simulates the actual sonar/GPS unit on your computer. You can run it from your computer keyboard or use your mouse to press the virtual keys. Easy download and installation instructions are available on our web site. The emulator works exactly like your real sonar/GPS unit. When using the Sonar and GPS Simulators you can play back sonar logs, run GPS routes and trails, even create real waypoints you can use in the field. You can take snapshots of the Sonar Chart and print them or e-mail them to friends. And that is just some of the material available on our web site. To find out what we have available, log on and look around. For now, we'll get back to how to use this particular unit.
How to use this manual: typographical conventions
Many instructions are listed as numbered steps. The keypad and arrow "keystrokes" appear as boldface type. So, if you're in a real hurry (or just need a reminder), you can skim the instructions and pick out what menu command to use by finding the boldface command text. The following paragraphs explain how to interpret the text formatting for those commands and other instructions: 11
Arrow Keys The arrow keys control the movement of dotted cross-hair lines on your mapping screen called the cursor. The arrow keys also control a horizontal line depth cursor on the sonar screen. The arrow keys help you move around the menus so you can execute different commands. They are represented by symbols like these, which denote the down arrow key, the up arrow, the left arrow and the right arrow: , . Keyboard The other keys perform a variety of functions. When the text refers to a key to press, the key is shown in bold, sans serif type. For example, the "Enter/Icons" key is shown as ENT and the "Menu" key is shown as MENU. Menu Commands A menu command or a menu option will appear in small capital letters, in a bold sans serif type like this: ROUTE PLANNING. These indicate that you are to select this command or option from a menu or take an action of some kind with the menu item. Text that you may need to enter or file names you need to select are show in italic type, such as trail name. Instructions = Menu Sequences Most functions you perform with your unit are described as a sequence of key strokes and selecting menu commands. We've written them in a condensed manner for quick and easy reading. For example, instructions for navigating a trail would look like this: 1. From the Map Page, press MENU|MENU| to MY TRAILS|ENT. 2. Press to Trail 1|ENT|| to NAVIGATE|ENT. 3. You are asked to wait while it converts the trail into a route. 4. The wait message disappears and the unit begins showing navigation information along the trail. Translated into complete English, step 1 above would mean: "Start on the Map Page. Press the Menu key twice. Next, repeatedly press (or press and hold) the down arrow key to scroll down the menu and select (highlight) the My Trails menu command. Finally, press the Enter key." Step 2 would mean: "Press the down arrow key repeatedly to scroll to the trail named Trail 1, and press Enter. Next, press the right arrow key and then the down arrow key to highlight the Navigate command, then press Enter." 12

GPS Internal Antenna

The unit has a built-in 12-parallel channel GPS + WAAS antenna.
NMEA 2000 Cable Connections
NMEA 2000 is a new buss network specifically designed for boats. This is a very young industry standard and, at the time of printing, few boats being built now have a NMEA 2000 buss installed. Over the next few 32
years, however, NMEA 2000 will become much more common. To help you get the most out of this technology, your Lowrance unit is designed to work with a NMEA 2000 network. You can install a network yourself using LowranceNET components and devices.
To NMEA 2000 network port To unit's Network socket
Lowrance unit direct connection to NMEA 2000 buss.
Connecting to a NMEA 2000 Network Your unit can be connected to a NMEA 2000 buss, receiving sensor information from any Lowrance units attached to the buss. Contact LEI Extras (look inside back cover for accessory ordering information) for a NMEA 2000 buss adapter cable if you would like to do this. You can connect the unit directly to a network port. To do so, attach the adapter cable's manual locking collar connector to the Network port on the back of the sonar unit and attach the other end to an available port on the NMEA 2000 buss. As soon as the unit is connected to the network, it will begin receiving shared information. Please note the buss must be powered to operate. (See instructions in this section on powering a NMEA 2000 buss.) IMPORTANT NOTE: The data from your internal GPS receiver will not be transmitted across the LowranceNET NMEA 2000 network. You must have an LGC-2000 GPS antenna module in the network for that to happen. Installation instructions for the LGC2000 and other electronic probe sensors, like the EP-10 Fuel Flow and EP-15 Fluid Level sensor are available in the document "Instructions for Using LowranceNET NMEA 2000 Devices with LMS-334, LMS-339 and GlobalMap 3600." If the document is missing, contact customer service or download it free at www.lowrance.com. NMEA 0183 Wiring (Data cable) To exchange NMEA 0183 data, this unit has one NMEA 0183 version 2.0 communication port. Com port one (Com-1) can be used to receive NMEA 0183 format GPS data. The com port can also transmit NMEA 0183 format GPS data to another device. The four wires for the com port are combined with the Power Supply cable and NMEA 2000 Power cable to form the power/data cable (shown earlier). Com-1 uses the yellow wire to transmit, the orange wire to receive and the shield wire for signal ground. Your unit does not use the blue wire. 33

Mounting the Unit: Bracket or Portable
You can install the sonar unit on the top of a dash with the supplied gimbal bracket. It can also be mounted on a portable power supply. If you use the supplied bracket, you may be interested in the optional R-A-M bracket mounting system. This converts the unit's gimbal bracket to a swivel mount.
Optional R-A-M mounting system.
Bracket Installation Mount the unit in a convenient location, provided there is clearance behind the unit when it's tilted for the best viewing angle. This must be a location with a clear view of the sky, so the internal GPS antenna can lock-on to satellite signals. Make sure there is enough room behind the unit to attach the power and transducer cables. Holes in the bracket's base allow wood screw or through-bolt mounting. You may need to place a piece of plywood on the back side of thin fiberglass panels to reinforce the panel and secure the mounting hardware.
Front Install the gimbal bracket. Position the bracket so the arms slope toward the front of your unit.
Drill a 1-inch (25.4 mm) hole in the dash for the power and transducer cables. The best location for this hole is immediately under the gimbal bracket location. This way, the bracket can be installed so that it covers the hole, holds the cables in position and results in a neat installation. Some customers prefer to mount the bracket to the side of the cable hole. It's a matter of personal preference.

You can customize how the Sonar Page displays its pictures and other data in many ways. We'll discuss all of those features and options in Sec. 4, but to show you how easy this unit is to operate, the following page contains a 10-step quick reference that will cover most fish finding situations. The quick reference describes how your unit will operate with all the sonar features in their automatic modes, which are set at the factory.
Basic Sonar Quick Reference
1. Mount the transducer, antenna and unit. Connect the unit to electric power and the transducer. (If GPS operation is desired, connect GPS antenna, too.) Make sure the MMC is in. (See complete installation details beginning on page 13.) 2. Launch your boat. 3. To turn on the unit, press and release PWR key. 4. Opening screen displays Map Page. Rotate through the four main Page screens (Map Page, Satellite Status Page, Navigation Page, Sonar Page) by pressing PAGES| to select Page Name|EXIT. Switch Pages to display Sonar Page. 5. If GPS data is desired, wait while unit locates satellites and calculates current position. When the unit acquires position, a tone sounds and a position acquired message appears. 6. With position acquired (if desired), head for your fishing grounds. Your unit will automatically display digital depth and surface water temperature in the top left corner of the screen. The auto settings will track the bottom, displaying it in the lower portion of the screen. The full sonar chart will scroll from right to left, showing you what's under the boat as you cruise across the water. You can change the display by: Zoom in to enlarge the chart for more detail: press ZIN. Zoom out to return to full chart mode: press ZOUT. 7. Watch the display for the appearance of fish symbols (or arches, if Fish I.D. is turned off). When you see fish symbols or arches, you've found fish! Stop the boat and get your lure or bait into the water at the depth indicated on the sonar chart. 8. Gauge the fish depth by visually comparing the fish symbols or arches with the depth scale on the right side of the screen. 9. If you are drifting at a very low speed or anchored, you are not moving fast enough for a fish to return the tell-tale fish arch signal. As you drift over a fish, or as a fish swims through the transducer's signal cone, the fish echo will appear as a straight line suspended between the surface and the bottom when Fish I.D. is turned off. 10. To turn off the unit, press and hold PWR key for three seconds.

Fish Alarm Use fish alarm to receive an audible alarm when fish or other objects are detected by the Fish I.D. feature (Fish I.D. must be turned on for the Fish Alarm to work). A different tone sounds for each fish symbol size shown on the display.

To turn on fish alarm:

1. Press MENU|MENU| to ALARMS|ENT| to SONAR ALARMS|ENT. 2. Press to FISH ALARM|ENT. Press EXIT repeatedly to get back to the main page.

NMEA 2000 Alarm

The NMEA 2000 Alarm can monitor multiple EP-10 Fuel Flow and EP15 Fluid Level sensors. You can set a threshold for each alarm in its corresponding Percent box. Thresholds give you control over when the alarm will go off. You may want the alarm to go off when the black water tank is filled to 75 percent of its capacity, likewise, you may want to know when the fuel level falls below 30 percent of tank capacity. To get to the NMEA 2000 Alarms menu, press MENU|MENU, select ALARMS and press ENT. Choose NMEA 2000 ALARMS and press ENT.
NMEA 2000 Alarms selected from alarms menu (left). NMEA 2000 Alarms menu (right).

To enable the Full Alarm, highlight FULL ALARM Enabled box and press ENT to turn on (check) the alarm. Press to the Percent box and press ENT. Use the keys to select the first number, then press to move to the next number. When the desired percentage has been entered, press ENT. 58
3. To enable the Empty Alarm, highlight the EMPTY ALARM Enabled box and press ENT to turn on (check) the alarm. Press to the Percent box and press ENT. Use the keys to select the first number, then press to move to the next number. When the desired percentage has been entered, press ENT.
You do not have to set both the Full and Empty alarms. Choose Full and Empty alarms or activate them individually.

Calibrate Speed

The speed sensor can be calibrated to compensate for inaccuracies. Before you change the setting, first calculate the percentage that the speed is off. You will enter this percentage in a moment. For example, if you figure the sensor is reading 10 percent faster than actual speed, you will enter 10 in the calibration window. If the sensor is reading 5 percent slower than true speed, you will enter + 5 in the window. A good way to gauge your speed sensor's performance is to compare its reading with the ground speed measured by your unit's GPS functions. When you make a run to compare GPS ground speed to speed sensor speed, perform your test in relatively calm water free of current, if possible. (Unless, of course, you are taking the speed of current into consideration when making your calculation.) After you have a correction figure, here's how to enter it: 1. Press MENU|MENU| to SONAR SETUP|ENT| to CALIBRATE WATER SPEED|ENT. 2. Enter the number you calculated earlier. Press to change the first character (+ or ), then press to move the cursor to the next number and repeat until the percentage is correct, then press EXIT.

See the entry on Advanced Signal Processing in this section.

Overlay Data

On any Page display except Satellite Status, you can float or overlay additional GPS or navigation data on the screen with the Overlay Data 70
command. For example, if you left your watch at home, you could display the local time on top of the map. Or, if you wanted to see details about your route and trip, you could show your bearing, course, average speed and trip distance. The various data available from your unit are divided into categories in the Overlay Data menu. These categories include GPS Data, Navigation, Trip Calculator, Time, Sonar Data and Miscellaneous Data. You can select items from any of these categories for display, in any combination the category divisions are there only to help you sort through the information.

You can adjust the sensitivity in each window. To adjust sensitivity in auto mode: 1. While on the Split Frequency Chart page, press MENU|ENT. 2. The unit asks which window (50kHz or 200kHz) you would like to adjust. Press to select the desired frequency|ENT. 81
3. The Sensitivity Control Bar appears. Press to adjust sensitivity. When it's set at the desired level, press EXIT. Digital Data/Chart This mode shows the chart on the right side of the screen. The left side has five digital data boxes containing: Water Depth; Water Speed (from an optional speed sensor); Water Distance (distance traveled or log, it also requires a speed sensor); Surface Water Temperature and Voltage.

Digital Data/Chart

Customize Page Displays Every Page display option except Full Map (on the Map Page) has customizable data boxes to provide constant on-screen information. The data available from your unit is divided into categories in the Data Viewer menu. These categories include GPS Data, Navigation, Trip Calculator, Time, Sonar Data and Miscellaneous Data. You can select items from any of these categories for display in any data box. To change the information displayed in a data box: On the Page display you want to change, press MENU| to CUSTOMIZE|ENT. A data box name flashes, indicating it is selected. Press ENT to change the box or hit , to select another box, then press ENT. You will see a list of categories with "+" or "" symbols next to each of them. A category with a "+" is closed, meaning its contents are hidden.

The Navigation with Sonar page.
When navigating to a waypoint, your ground speed, track, distance, bearing to the waypoint and course are all displayed. NOTE: Remember: when Speed, Track and Position information displays are flashing, satellite lock has not been achieved and no position fix has been determined. A question mark will also flash on the present position arrow in the center of the compass rose. Speed (ground speed) is the velocity you are making over the ground. (If you want, you can customize the Speed data box to display Closing Speed instead. Closing Speed is also known as velocity made good. It's the speed that you're making toward the waypoint. For instructions, see the Customize Page Displays entry in Sec. 8.) Track is the heading, or the current direction you are actually traveling. Bearing is the direction of a line-of-sight from your present position to the destination. No matter what direction you are steering, the Bearing window shows the compass direction straight to the destination from your location at the moment. Distance shows how far it is to the waypoint you're navigating toward. The Off Course window shows the current cross track error. This shows 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. The course line is shown on the Navigation Page screen (and the Map Page screen) as a dotted line.

Cross track error range (off course indicator) Destination name
The cross track error range is shown on the compass rose as a wide, white, corridor enclosing the course line. The outer edges of this white corridor represent lines that show the current cross track error range. The default for the cross track error range is 0.20 miles. For example, if the present position symbol touches the right cross track error line, then you are 0.20 miles 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 circular symbol showing your destination (waypoint) appears on the screen as you approach the waypoint, as shown on the screen in the preceding figure. Travel Time is the time that it will take to reach your destination at your present closing speed. (You can also customize the time data box to show Arrival Time instead. Arrival Time is the local time it will be when you arrive at the destination, based upon your present closing speed and track.) In the preceding example, the driver is headed west (a 265 track) toward a waypoint 265 (bearing) away. The cross track error range (white corridor) is 0.20 miles either side of the course. The driver is headed toward trail waypoint 4, which is 0.3 miles away. The vehicle is right on course. Traveling at a speed of 8 mph, the driver will arrive at the waypoint in 2 minutes, 17 seconds. The Navigation Page has its own menu, which is used for some advanced functions and for setting 102

You can turn off any of the navigation commands after you reach your destination or at any other time by using the Cancel Navigation command. Press MENU|MENU| to CANCEL NAVIGATION|ENT| to YES|ENT.

You do not have to set both the Full and Empty alarms. Choose both Full and Empty alarms or activate them individually.

Auto Satellite Search

To lock on to the satellites, the GPS receiver needs to know its current position, UTC time and date. Altitude is also used in the equation, but it's rarely required to determine a position. It needs this data so 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 doesn't know what your position or altitude is. It knows 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. If the time and/or date are incorrect, you can set them using the Set Local Time menu. The unit 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 it's almost certain that you're not at our factory, it's probably looking for the wrong satellites. If it doesn't find the satellites it's looking for after approximately one minute, it switches to Auto Search. The receiver looks for any satellite in the sky. Due to advanced technology, the auto search time has shrunk significantly from the early days of GPS. Once the unit locks on to the satellites, it should take less than a minute to find your position the next time it's turned on, as long as you are approximately 100 miles from the last location it was used.

Communications Port Configuration
The unit has one NMEA 0183 version 2.0 compatible communication port. The Com Port Menu, accessed from the System Setup Menu, allows you to configure the communications port to send or receive data from another electronic device, like autopilot. The com port can be used for a NMEA or SiRF Binary data transfer. For connectors and wiring information for another device, see page 33.

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. 154
In Track Up mode, map shows "N" and arrow to indicate north.
Map orientation (left) is shown in north up and track up (right).
This is fine if you're always traveling 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 doesn't 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. Another option is course-up mode, which keeps the map at the same orientation as the initial bearing to the waypoint. When either the track-up or course-up mode is on, a "N" shows on the map screen to help you see which direction is north.
