Section 1: Read Me First!
After you've gained some experience with your sonar, you'll want to check out Section 4, which discusses advanced Sonar Options and Other Features. When you come to a sonar menu command on the unit's screen, you can look it up in the manual by skimming over the table of contents, flipping through Section 3, or scanning through the sonar options in Section 4. If you're having difficulty with your sonar, you can find an answer to the most common problems in Section 5, Sonar Troubleshooting. The manual switches from sonar to navigation in Section 6, which introduces you to Basic GPS Operations. This section features a onepage GPS Quick Reference on page 111. Section 6 contains short, easy-to-scan GPS lessons that follow one another in chronological order. They're all you'll need to know to find your way on the water quickly. After you've learned the basics (or if you already have some GPS experience), you may want to try out some of the unit's many advanced navigation features. That brings us to Section 7, Advanced GPS Operations. This section contains the rest of the unit's GPS command functions, organized in alphabetical order. When you come to a GPS menu command on the screen, you can look it up in the manual by skimming over the table of contents, flipping through Section 6, or scanning through the command portion of Section 7. This unit is ready to use right out of the box, but you can fine tune and customize its operation with dozens of options. Since sonar is the unit's key feature, we put the main sonar options in Section 4. Some options, such as screen brightness settings, affect both sonar and GPS operations. We describe how to use those common options along with GPS options in Section 8, System Setup and GPS Setup Options. Section 8 is organized in alphabetical order. In Section 9, we go into more detail on one of the unit's most remarkable GPS capabilities Searching. We'll introduce a search example in the Basic GPS Operation section, but there are so many map items you can search for that we had to give this function its own section in the manual! For example, did you know your unit can look up business phone numbers, like a virtual Yellow Pages? Well show you how in Section 9. Finally, in Section 10, we offer Supplemental Material, including a list of the GPS data, warranties and customer service information. It's important to us (and our power users), but, if you don't care how many watts of power the unit has, or how many waypoints it can store, skip ahead to important information on how sonar works, on page 6 (Background on GPS begins on page 7). 2
NOTICE! The storage and operation temperature range for your unit is from 20 degrees to +167 degrees Fahrenheit (-28 degrees to +75 degrees Celsius). Extended storage or operation in temperatures higher or lower than specified will damage the liquid crystal display in your unit. This type of damage is not covered by the warranty. For more information, contact the factory's Customer Service Department; phone numbers are listed on the last page of the manual.

Transom

Bottom of hull Speed sensor mounting configuration: side view (left) and rear view (right.)
If the base of the transom has a radius, fill the gap between the transom and the sensor with the sealant. This will help ensure a smooth water flow. Route the sensor's cable through or over the transom to the sonar unit. If you need to drill a hole in the transom to pass the connector through, the required hole size is 7/8". CAUTION: If you drill a hole in the transom for the cable, make sure it is located above the waterline. After installation, be sure to seal the hole with the same marine grade above- or below-waterline sealant used for the screws. The sensor is now ready for use. Connect the sensor to the sonar socket on the back of your unit and connect the transducer to the speed sensor's socket. If you have any questions concerning the installation of the sensor, please contact your local boat dealer.
GPS Antenna/Receiver Module
The LCX-27C, LCX-28C HD, LCX-37C, LCX-38 C HD, LCX-112C and LCX113C HD packages include the LGC-3000 GPS module. This device contains the unit's external antenna and receiver for GPS and WAAS signals. The antenna/receiver module comes with a 15-foot extension cable. This module can be mounted on a flat surface or pole, or an optional magnet is available for temporary mounting on any ferrous surface.
LGC-3000 Module, bottom view (left) and top view (right).
You need to select an antenna installation location that has a clear, unobstructed view of the sky. After the module is installed, connect it to the unit. The LGC-3000 can communicate with your GPS unit either directly (using the supplied extension cable) or through a NMEA 2000 network. NOTE: See the modules instruction sheet, publication part number 9880154-651, for complete installation instructions. In an automobile, you may achieve good results by simply placing the external antenna on the top of the dash, at the base of the windshield. A piece of the rubber non-skid shelf liner material available in recreational vehicle supply stores will help hold the antenna in place. This may not work well if you have a cab-over design pickup truck camper or motor home. If dashboard reception is poor, simply relocate the antenna module elsewhere on the vehicle for a clearer view of the sky.

Power Connections

Your unit comes with a power/data cable that splits into three branches, each with several exposed wires. The thicker two-wire cable (red and black) is the power supply for your display unit. This cable has no label. The branch with three wires (red, black and shield) is the power cable for a NMEA 2000 network. It is labeled "NMEA 2000 POWER." The branch with 5 wires (blue, yellow, orange, green and shield) is a data cable, labeled "RS-232 COMM." It supports two serial communication ports. These allow your unit to exchange NMEA 2000 data with another device, such as an autopilot, DSC marine radio or computer.

NMEA 2000 Cable Connections
NMEA 2000 is a new bus network specifically designed for boats. This is a young industry standard and, at the time of printing, some boats being built now have a NMEA 2000 bus installed. Over the next few 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.
Connecting to a NMEA 2000 Network
A network bus is an installed and operational network cable (backbone) running the length of your boat, already connected to a power supply and properly terminated. Such a bus provides network connection nodes at various locations around your boat. The NMEA 2000 network is similar to the telephone wiring in a house. If you pick up a phone in your living room, you can hear someone talking into the phone in the bedroom. Lowrance and LEI provide all the cables you will need to create a NMEA 2000 network. Lowrance provides T connectors and extension cables so you can add devices along the backbone wherever you want. Once you have a working network, every sensor added will come with its own T connector for easy expansion. The simplest NMEA 2000 network is a GPS or sonar/GPS display unit with the LGC-3000, one double-T connector, two 120 ohm terminators and any extension cables needed to connect them. 31

The diagram above has a double T connector with two 120-ohm terminators one at each end of the connector. It is easy to expand this network by removing a terminator from one end of the double T connector, then inserting a new T connector or extension cable between the double T connector and terminator (See the NMEA 200 network general information document that came with your unit for more information).
NMEA 0183 Wiring (Data cable)
To exchange NMEA 0183 data, this unit has two NMEA 0183 version 2.0 communication ports. Serial Communications Port one (Com1) and Serial Communications Port two (Com2) can be used to transmit or receive NMEA format GPS data. The five wires for the Serial Communications Ports are combined with the Display Unit Power cable and NMEA 2000 Power cable to form the power/data cable (shown earlier). Com1 uses the yellow wire to transmit, the orange wire to receive and the shield wire for signal ground. Com2 uses the blue wire to transmit, the green wire to receive and the shield wire for signal ground. 32

Optional R-A-M mounting system.
Bracket Installation Mount the unit in any convenient location, provided there is clearance behind the unit when it's tilted for the best viewing angle. You should also 39
make sure there is enough room behind the unit to attach the power, transducer and GPS antenna/receiver module cables. (A drawing on the next page shows the dimensions of a gimbal-mounted unit.) Holes in the bracket's base allow wood screw or through-bolt mounting. You may need to place a piece of plywood on the backside of thin fiberglass panels to reinforce the panel and secure the mounting hardware.

Cable hole

Screw mounting hole
Install the gimbal bracket. Place the bracket so the arms slope toward the front of your unit.
Once a location is determined, use the bracket as a template and mark the mounting holes and the hole for the cables. Drill a 1-inch (25.4 mm) hole in the dash for the power, transducer and antenna cables. Screw the bracket to the mounting surface.

Front view (left) and side view (right) showing dimensions of the LCX37C and LCX-38C HD mounted on gimbal brackets.
To pass all connectors through the 1" hole, first pass the transducer connector up through the hole from under the dash, followed by the antenna connector and any accessory cables. Next, pass the power cable's bare-wire end down though the hole from the top. If you wish, you can fill in the hole around the cables with a good marine caulking compound. No matter what type of installation you prefer, be sure to leave enough slack in the cables to allow tilting or swiveling the unit. Attach the unit to the gimbal bracket using the supplied gimbal knobs and washers. Attach the cables and the unit is ready to use. In-Dash Installation You can mount the LCX-27C and LCX-28 C HD in the dash with an optional FM-3 In-Dash Adapter Kit. The kit includes mounting hardware and a template for cutting the hole.

1. Press MENU|MENU| to ALARMS|ENT| to SONAR ALARMS|ENT. 2. Press to FISH ALARM|ENT|EXIT|EXIT|EXIT.

Calibrate Speed

You can calibrate the speed sensor to compensate for inaccuracies. Before you change the setting, first calculate the percentage that the speed is off. 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 the GPS ground speed to the speed sensor, perform your test in relatively current-free calm water, if possible. (Unless, of course, you are taking the current speed into consideration when making your calculation.) For example, if you figure the sensor is reading 1 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. After you have a correct 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 or 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. 64

Chart Speed

The chart speed is the rate echoes scroll across the screen. The default is maximum. We recommend you leave the setting there for virtually all fishing conditions. You, however, might consider experimenting with chart speed when you are stationary or drifting very slowly. You may sometimes achieve better images as you slow the chart speed to match how fast you are moving across the bottom. If you are at anchor, ice fishing or fishing from a dock, experiment with a chart speed around 50 percent. If you are drifting slowly, try a chart speed around 75 percent. When you are stationary and a fish swims through the sonar signal cone, the image appears on the screen as a long line instead of a fish arch. Reducing the chart speed may result in a shorter line that more closely resembles a regular fish return.

Create Waypoint at Current Position While you are traveling, press WPT|WPT. The waypoint is saved and

The unit begins navigating to the item. To cancel navigation, press MENU|MENU| to CANCEL NAVIGATION|ENT| to YES|ENT. The unit stops showing navigation information.
Creating and Saving a Trail
A trail, or plot trail, is a string of position points plotted by the unit as you travel. It's a travel history, a record of the path you have taken. Trails are useful for repeating a journey along the same track. They are particularly handy when you are trying to retrace your trip and go back the way you came. The unit is set at the factory to automatically create and record a trail while it is turned on. The unit will continue recording the trail until the length reaches the maximum trail point setting. Default is 2,000, but it can record trails up to 9,999 points long. When the point limit is reached, the unit begins recording the trail over itself. By default, the trail flashes once a second, making it easier to see against the background map. With the default auto setting, the unit creates a trail by placing a dot (trail point) on the screen every time you change directions. The methods used for creating a trail and the trail update rate can be adjusted or even turned off. See Sec. 8 for Trail Options. To preserve a trail from point A to point B, you must "turn off" the trail by making it inactive before heading to point C or even back to point A. When the current trail is set inactive, the unit automatically creates and begins recording a new trail. To Save a Trail 1. Press MENU|MENU| to MY TRAILS|ENT.

Show WAAS Alarm

When the signal is available, your unit will automatically use WAAS to boost the accuracy of the position fix. When the WAAS signal is lost or acquired, an alarm message appears. Since the U.S. government is still developing the WAAS system, it's not unusual for a GPS/WAAS receiver to frequently lose and reacquire its lock on a WAAS satellite. That can result in the alarm repeatedly going on and off. You have the option of turning off the WAAS Acquired/Lost alarm without affecting how the unit uses WAAS. Here's how: 1. Press MENU|MENU| to GPS SETUP|ENT| to SHOW WAAS ALARM. 2. With the option highlighted, press ENT to uncheck it (turn off) or check it (turn on).

Instance

The Instance command is intended for use only by experienced NMEA 2000 network technicians. 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. 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.

Restore Defaults

The Restore Defaults command allows you to reset an individual EP-35 Temp Sensor's settings to factory defaults. If, for example, you execute the Restore Defaults command from your Water Temp's Advanced Options menu, only the settings for the Water Temp will be reset to factory defaults. Other temps on the network will not be affected. 195
