WARNING: Do not remove any material from your inner hull unless you know the hull's composition. Careless grinding or cutting on your hull can result in damage that could sink your boat. Contact your boat dealer or manufacturer to confirm your hull specifications.
Fill with Fill with resin Flotation material Inner hull

Epoxy to hull first

Outer hull
Epoxy the transducer to a solid portion of the hull.
For example, some (but not all) manufacturers use a layer of fiberglass, then a core of balsa wood, finishing with an outer layer of fiberglass. Removing the inner layer of fiberglass and the balsa wood core exposes the outer layer of fiberglass. The transducer can then be epoxied directly to the outer layer of fiberglass. After the epoxy cures for 24 hours, fill the remaining space with polyester resin. When the job is finished, the hull is watertight and structurally sound. Remember, the sonar signal must pass through solid fiberglass. Any air bubbles in the fiberglass or the epoxy will reduce or eliminate the sonar signals. Testing Determines Best Location Ideally, the shoot-thru transducer should be installed as close to the transom as possible, close to the centerline. This will give you the best performance during high speed maneuvers.
Transducer location (high speed) Transducer location (trolling speed)
Shoot-thru-hull transducer locations for high speed or trolling speed operation.
To choose the proper location for shoot-thru-hull mounting, follow these testing procedures: (You may need a helper to complete these steps.) 1. Anchor the boat in about 30 feet of water. Add a little water to the sump of the boat. Plug the transducer into the sonar unit, turn it on, then hold the transducer over the side of the boat in the water. Adjust the sensitivity and range controls until a second bottom echo is seen on the display. (You'll need to turn off Auto Sensitivity, Auto Depth Range and ASP. Try a range setting that is two to three times the water depth. The harder (more rocky) the bottom, the easier it will be to get a second bottom signal.) Don't touch the controls once they've been set.

True bottom

Second bottom

Manual range setting

Example of a second bottom signal. Unit is in 30 feet of water, with range set at 80 feet and sensitivity set at 87 percent.
2. Next, take the transducer out of the water and place it in the water in the sump of the boat, face down. (The transducer face is shown in the figure on the following page.) Notice how the signal strength decreases. The second bottom signal will probably disappear and the bottom signal intensity will likely decrease. 3. Now move the transducer around to find the best location with the strongest possible bottom signal. If you find a spot with an acceptable bottom signal, mark the location and move on to step 4. If you can't get an acceptable bottom signal, try turning up the sensitivity by three or five keystrokes and then move the transducer around once more. If you find a spot that works, mark it and move on to step 4. If you have to turn up sensitivity by more than five keystrokes to get a good signal, the transducer should be mounted on the outside of the hull. This is especially true if you have to turn sensitivity all the way up to get a decent bottom signal. 4. Most people get good results by following steps 1 through 3, so this step is optional. If you want to make an extra effort to be absolutely sure 26

Power Connections

Your unit comes with a power/data cable that splits into three branches, each with several exposed wires. The thicker three-wire cable (white, red and black) is the power supply for your display unit. This cable has no label. The thinner 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 four wires (blue, yellow, orange, and shield) is a data cable, labeled "RS-232 COMM." It supports a serial communication port. This allows your unit to exchange NMEA 0183 data with another device, such as an autopilot, DSC marine radio or computer.
Display unit power wires: white, red and black 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.
NOTE: There are two basic power connection options, which are shown in the following two diagrams. Read the following instructions carefully to determine which power connection applies to your unit. Depending on your configuration, you may not use all of these wires. 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 30
wire nuts, wrapping them with electrical tape or both. (You should cut off the bare wire before taping off the ends.)
Powering Your Display Unit
The display unit works from a 12-volt DC battery system. Attach the display power cable (with provided 3-amp fuse) to an accessory switch or power bus. If this results in electrical interference, connect direct to a battery but install an in-line switch on the cable. Caution: We strongly recommend that you shut off the power supply to the power cable when the unit is not in use, especially in saltwater environments. 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. Risk of electrolysis corrosion is even greater when the cable is unplugged from the unit, but still connected to a power source. 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 in-line switch. This will let you shut off power to the power cable when the unit is not in use. When you are not using the unit, you should always shut off power to the power cable, especially when the power cable is disconnected from the unit. WARNING: This product must be independently fused with the enclosed 3-amp fuse (or equivalent), even if you connect to a fused accessory or power bus. If a malfunction happens inside the unit, extensive damage can occur if the enclosed fuse is not used. As with all electrical devices, this unit could be damaged to a point it cannot be repaired and could even cause harm to the user when not properly fused. Failure to use a 3-amp fuse will void your warranty. If possible, keep the power cable away from other boat wiring, especially the engine's wires. This will provide the best isolation from electrical noise. If the cable is not long enough, splice #18 gauge wire onto it.

Now that you have your unit installed, move on to Section 3, Basic Sonar Operations. There, we'll present a series of step-by-step tutorials to teach you the basics of how to operate your sonar. NOTE: When you first turn the unit on, the Map Page appears. If you'd rather start learning about GPS operation first, turn over to Section 6, Basic GPS Operations.

Face Cover

Your unit comes with a white protective cover that snaps on and off the front of the unit. This cover is intended for use when the vehicle is idle. WARNING: When the unit is mounted in an unprotected area, such as an open boat cockpit, the protective face cover must be removed when the vehicle is moving at high speed. This includes towing a boat on a trailer at highway speeds. Otherwise, wind blast can pop off the cover.
Section 3: Basic Sonar Operation
This section addresses the unit's most basic sonar operations. Before you turn on the sonar unit, it's a good idea to learn about the different keys, the Main Menu, the four Page screens and how they all work together. BUT, if you just can't wait to get on the water, turn to the one-page Quick Reference on page 51.

EXIT The Exit key lets you return to the previous screen, clear data or close a menu. 7. WPT (Waypoint) The Waypoint key is used to save and recall waypoints, search for waypoints and access the waypoint list. It also launches the Point-of-Interest (POI) search menus and is involved in some navigation functions. 8. ZOUT (Zoom Out) This key lets you zoom the screen out. On the Sonar Page, it returns you to a full sonar chart display, showing the entire water column from surface to bottom. On the Map Page, it lets you see a larger geographic area on the map. Less detail is seen as you zoom out. 9. ZIN (Zoom In) This key lets you zoom the screen in. On the Sonar Page, this key enlarges fish signals and bottom detail. On the Map Page, zooming in lets you see greater detail in a smaller geographic area on the map.

For the ultimate training aid, be sure to download the free emulator software for your unit. Aside from being fun, this program can help you learn both basic and advanced operations without burning boat fuel! Lowrance is one of the first sonar manufacturers to provide this type of training tool for customers. 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.
Free training emulator is available for your unit on our web site.
The emulator works exactly like your real sonar/GPS unit. Using the Sonar Simulator and GPS Simulator features, it allows you to play back sonar logs, run GPS routes and trails and create real waypoints you can use in the field! You can even take snapshots of the Sonar Chart and print them or e-mail them to friends.

Section 4: Sonar Options

ASP (Advanced Signal Processing)
The ASP feature is a noise rejection system built into the sonar unit 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 four settings Off, Low, Medium 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. There are times when you may want to turn the ASP feature off. This allows you to view all incoming echoes before they are processed by the ASP feature.

To change the ASP level: 1. From the Sonar Page, press MENU| to SONAR FEATURES|ENT. 2. Press to NOISE REJECTION|ENT. 57
3. Press or to select a setting, then press ENT. 4. To return to the previous page, press EXIT|EXIT.

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.

To adjust Menu Transparency level: Press MENU|MENU| to TRANSPARENCY|ENT. The TRANSPARENCY slider bar appears. Press or to move the bar. The lower end of the scale makes the menus opaque; the upper end is maximum transparency. 95

Zoom & Zoom Bar

"Zooming" the display is a common, fast and easy method used to enlarge small detail, fish signals and the bottom with its associated structure. This unit lets you zoom the display quickly and easily by pressing the Zoom In key, ZIN. Pressing ZIN once doubles the size (2X) of all echoes on the screen. Pressing it again quadruples the size of the echoes (4X). The zoom bar on the far right side of the screen shows which echoes will be displayed on the screen when the ZIN key is pressed. For example, pressing the ZIN key once will enable a 2X zoom which will show all echoes that are between the top and bottom of the 2X zoom bar. Pressing the key again will give a 4X zoom and only the echoes between the top and bottom of the 4X bar will show on the screen. Press the Zoom Out key, ZOUT, to return the display to the normal mode.

Zoom Pan

Your unit has the handy ability to quickly zoom in on any portion of the water column with just the touch of an arrow key. The Zoom Pan feature lets you rapidly move the zoomed area up and down to different depths. By "pointing" your zoom at different portions of the chart as it scrolls, you can get a good, close-up look at structure or cover below you. To use Zoom Pan, switch to a manual depth Range setting (see page 67) and turn on 2X or 4X Zoom. Then, simply press to pan up and down the water column. 96
Section 5: Sonar Troubleshooting
If your unit is not working, or if you need technical help, please use the following troubleshooting section before contacting the customer service department. It may save you the trouble of returning your unit for repair. For contact information, refer to the last page, just inside the back cover of this manual. Unit won't turn on 1. Check the power cable's connection at the unit. Also check the wiring. 2. Make sure the power cable is wired properly. The red wire connects to the positive battery terminal, black to negative or ground. 3. Check the fuse. 4. Measure the battery voltage at the unit's power connector. It should be at least 10 volts. If it isn't, the wiring to the unit is defective, the battery terminals or wiring on the terminals are corroded, or the battery needs charging. Unit freezes, locks up, or operates erratically 1. Electrical noise from the boat's motor, trolling motor, or an accessory may be interfering with the sonar unit. Rerouting the power and transducer cables away from other electrical wiring on the boat may help. Route the sonar unit's power cable directly to the battery instead of through a fuse block or ignition switch 2. Inspect the transducer cable for breaks, cuts, or pinched wires. 3. Check the transducer and power connector. Make sure it's securely plugged in to the unit. Weak bottom echo, digital readings erratic, or no fish signals 1. Make sure the transducer is pointing straight down. Clean the face of the transducer. Oil, dirt and fuel can cause a film to form on the transducer, reducing its effectiveness. If the transducer is mounted inside the hull, be sure it is shooting through only one layer of fiberglass and that it is securely bonded to the hull. When attaching a transducer to the inside of a hull, ONLY use the epoxy available from LEI (order information is inside the back cover). Do NOT use RTV silicone rubber adhesive or any other type of epoxy. The LEI epoxy is specially formulated so that it will cure properly for shoot-through applications. 2. Electrical noise from the boat's motor can interfere with the sonar. This causes the sonar to automatically increase its discrimination or noise rejection feature. This can cause the unit to eliminate weaker signals such as fish or even structure from the display. 3. The water may be deeper than the sonar's ability to find the bottom. 97

1. From the Custom Gauges page, press MENU SELECT OVERLAY DATA and press ENT. The Overlay Data Shown menu will appear. 2. Highlight the Data Type you want to resize, then use to set the data to the desired size to one of four options: Off, Small, Medium, Large and Enormous. 3. To change the size of another Data Type, repeat the steps above. To return to the Sonar with Custom Gauges display, press EXIT. NOTE: One of the data display options for the Satellite Status page is "Position Error" (horizontal position error), which can appear in one of the page's data boxes. If you turn on Position Error, it will show you the expected error from a benchmark location. In other words, if the Position Error box shows 50 feet, then the position shown by the unit is estimated to be within 50 feet of the actual location. This also gives you an indicator of the fix quality the unit currently has. The smaller the position error number, the better (and more accurate) the fix is. If the position error flashes dashes, then the unit hasn't locked onto the satellites, and the number shown isn't valid. (For details, see the Customize Page Displays entry in Sec. 8.) The Satellite Status Page has its own menu, which is used for setting various options. (Options and setup are discussed in Sec. 8). To access the Satellite Status Page Menu, from the Status Page, press MENU.

This unit has a Cursor Undo feature that lets you instantly return to the previous location you were looking at without scrolling. It works like this: Use the cursor (arrow keys) to scroll the map to some far away location or waypoint. Press EXIT to clear the cursor and jump back to your current position on the map. When you want to take another peek at that distant place, just press EXIT again. You can use this trick to toggle between your current position and your destination without a lot of scrolling.

Searching

Now that you have seen how the unit can find where you are, let's search for something else. Searching is one of the most powerful features in the Lowrance GPS product line. In this example, we will look for the nearest fast-food restaurant. For more information on different types of searches, refer to Sec. 9, Searching. NOTE: This example requires the Point of Interest (POI) database included with a high detail MapCreate 6 custom map.

Icons are graphic symbols used to mark some location, personal point of interest or event. They can be placed on the map screen, saved and recalled later for navigation purposes. These are sometimes referred to as event marker icons. This unit has 42 different symbols you can pick from when creating an icon. Icons are similar to waypoints, but they do not store as much information (like names) as waypoints do. You can't use a menu to navigate to icons as you can with waypoints. (But, you can use the map cursor and navigate to any icon on the map.) You can create an icon at the cursor position on the map, or at your current position while you are navigating.

Routes

A route is a series of waypoints, linked together in an ordered sequence to mark a course of travel. You can visualize a route as a string of beads. The beads represent waypoints and the string represents the course of travel connecting waypoint to waypoint.
The course from one waypoint to the next is a leg. Routes are composed of one or more legs. The legs of all GPS routes are based on straight lines between waypoints. A route provides the automatic capability to navigate through several waypoints without having to reprogram the unit after arriving at each waypoint. Once programmed into the GPS unit, a route provides the option of navigating forward through the route waypoints or in reverse order (you can even begin navigating in the middle of a route!) Create and Save a Route You have the option of creating and editing a route in the unit or you can make a route on your computer with our MapCreate 6 software.

Advanced Options menu The Temp sensor Advanced Options menu contains two categories: Instance and Restore Defaults.

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. To restore default settings: 1. Press MENU| MENU, use to select NMEA 2000 and press ENT. The NMEA 2000 menu will appear with five options: Bus Setup, Fuel Management, NMEA 2000 Alarms, Waypoint Sharing and Backlight Synchronization. 2.
