The X-75 and X-85 are the latest members of the Lowrance family that combines a high performance sonar with a wide, high definition screen. Using menu features and soft-key operation, these units are also easy to use. The wide screen shows the underwater world with high resolution and detail. The display and keyboard are also lighted for night operation. They have digital boat speed, surface water temperature, and distance travelled (log) screens. (Requires optional ST-TBK speed/temperature sensor for both speed and temperature screens.) The optional SAM-50HPD gives these units 50 kHz capability.The 3000 watt transmitter in the SAM-50HPD plus the low frequency gives the units far more depth penetration. This, along with the wider cone angle transducers, makes 50 kHz operation ideal for ocean and Great Lakes use.

MOUNTING Install the unit in any convenient location, provided there is clearance behind the unit when it is tilted for the best viewing angle. Holes in the bracket base allow wood screw or through-bolt mounting. You may need to place a piece of plywood on the back of thin fiberglass panels to secure the mounting hardware. Make certain there is enough room behind the unit to attach the power and transducer cables. The gimbal bracket will also accept the GBSA-1 swivel bracket adapter that lets you rotate the unit a full 360. The smallest hole that allows one power or transducer connector to pass through is 3/4". After the hole is drilled, push the transducer connector up through the hole first, then drop the power cable down through it.
After the cables have been routed, fill the hole with a good marine sealing compound. Offset the bracket to cover the hole. Route the power cable through the slot. Break out one of the holes in the back of the bracket for the transducer cable.
POWER CONNECTIONS The 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. It uses 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. If youre installing a speed/temperature sensor, read it's mounting instructions. Route the sensors cable to the power cable and plug it into the connector marked SPEED/TEMP CABLE
(20 Transducer Only) Typically, shoot-thru-hull installations give excellent high speed operation and good to excellent depth capability. There is no possibility of damage from floating objects. It can't be knocked off when docking or loading on the trailer. However, the shoot-thru-hull installation does have its drawbacks. One, some loss of sensitivity does occur, even on the best hulls. This varies from hull to hull, even from different installations on the same hull. This is caused by differences in hull layup and construction. Two, the angle of the transducer cannot be adjusted for the best fish arches. This can be a problem on some hulls that sit with the bow high when at rest or at slow trolling speeds. Follow the procedure listed in the shoot-thru-hull installation section in this manual to determine if you can satisfactorily shoot through the hull.
Transducer Assembly and Mounting - 20 Transducer Only The best way to install this transducer is to loosely assemble all of the parts first, place the transducers bracket against the transom and see if you can move the transducer so that its parallel with the ground. 1. Press the two small plastic ratchets into the sides of the metal bracket as shown below. Notice there are letters molded into each ratchet. Place each ratchet into the bracket with the letter A aligned with the dot stamped into the metal bracket. This position sets the transducers coarse angle adjustment for a fourteen (14) degree transom. Most outboard and stern-drive transoms have a fourteen degree angle.
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 you can, 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.
3. Once you determine the correct position for the ratchets, assemble the transducer as shown at left. Don't tighten the lock nut at this time.

CAUTION! CLAMP THE TRANSDUCER CABLE TO TRANSOM NEAR THE TRANSDUCER. THIS WILL HELP PREVENT THE TRANSDUCER FROM ENTERING THE BOAT IF IT IS KNOCKED OFF AT HIGH SPEED.
POOR ANGLE GOOD LOCATION
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. Don't 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.
5. Remove the transducer from the bracket and re-assemble it with the cable passing through the bracket over the bolt as shown above. 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. Make certain to leave some slack inthe cable at the transducer as shown above. 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. Don't allow the transducer bracket to go below the bottom of the hull!
(20 Transducer Only) The transducer installation inside a fiberglass hull must be in an area that does not have air bubbles in the resin or separated fiberglass layers. The sonar signal must pass through solid fiberglass. A successful transducer installation can be made on hulls with flotation materials (such as plywood, balsa wood, or foam) between layers of fiberglass if the material is removed from the chosen area. For example, some 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, 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. To choose the proper location for thru-hull mounting, anchor the boat in 60 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. Adjust the sensitivity and range controls until a second bottom echo is seen on the display. (you will need to turn both automatic and ASP off.) Dont touch the controls once theyve been set. Next, take the transducer out of the water and place it in the water in the sump of the boat. Observe the sonar signal to see if there is a noticeable decrease in sensitivity. The second bottom signal may disappear and the bottom signal may decrease in intensity. Move the transducer around to find the best location. If the sensitivity control has to be increased greatly to compensate, then the transducer should be mounted on the outside of the hull. If not, then mark the location that shot through the hull the best and follow the instructions on the next pages for a shoot-thru-hull mounting.
TRANSDUCER LOCATION (HIGH SPEED)
TRANSDUCER LOCATION (TROLLING SPEED)
(20 Transducer Only) 1. Make certain the area is clean, dry, and free of oil or grease, then sand both the inside surface of the hull and the face of the transducer with 100 grit sandpaper. The surface of the hull must be flat so the entire transducer face is in contact with the hull prior to bonding.
SPREAD EPOXY HERE
SAND THIS SURFACE
2. Follow the instructions on the epoxy package and mix it thoroughly. Do not mix it too fast, as it will cause bubbles to form in the epoxy. Apply a small amount on the face of the transducer as shown above, then spread a small amount onto the sanded area on the hull. Place the transducer into the epoxy, twisting and turning it to force any air bubbles out from under the transducer face. The face of the transducer should be parallel with the hull, with a minimum amount of epoxy between the hull and transducer. After the epoxy dries, route the cable to the sonar unit.

2. Once you've determined the proper ratchet placement, assemble the transducer and bracket as shown above. Don't tighten the nut at this time. INSTALLATION - Location 1. The transducer must be placed in a location that has a smooth flow of water at all times. Air bubbles created by the movement of the boat hull against the water interfere with the sonar signal. This causes noise or random marks to appear on the sonars display. You may need to carefully view the waters path at the transom while the boat is moving to determine the best location for the transducer. 2. Make certain the chosen location doesnt interfere with the boats trailer. Mount the transducer at least one foot from the engines lower unit. This will prevent air bubbles from the transducer interfering with the propeller.
POOR LOCATION GOOD LOCATION POOR ANGLE
3. Dont mount the transducer directly behind strakes or ribs on the bottom of the hull. Typically, a good location on aluminum boats is between the ribs closest to the engine. 4. Once you determine the best location for the transducer, hold the bracket against the transom. The transducer should be roughly parallel to the ground. The bottom of the hull should be about halfway between the centerline of the transducer and its bottom. (See the illustration below.)
Mark the transom in the center of each slot in the transducer bracket. Now drill one hole in the center of each slot. Use #12 stainless steel screws (not included) to loosely attach the brackets to the transom. 5. Adjust the transducer and bracket so that the front of the transducer is slightly lower than the back. See the section on fish arches in this manual for proper transducer angles. Tighten all screws. Clamp the transducer cable to the transom close to the transducer. This will prevent the transducer from entering the boat should it be knocked off at high speed.
6. Route the transducer cable to the sonar unit. Keep the transducer cable away from other wiring on the boat, if possible. Electrical noise from engine wiring or bilge pumps can be picked up on the transducer cable. This can show up as unwanted interference on the sonar display.
NOTE: Some aluminum boats with strakes or ribs on the outside of the hull create large amounts of turbulence at high speed. These boats typically have large outboard motors capable of propelling the boat at speeds over 35 mph. The transducer should be mounted as far below the hull as possible on these boats. This will place the face of the transducer below the turbulent water, allowing the sonar unit to work at high speeds. 7. Make a test run to determine the results. If there is interference on the display when running the boat at high speed, try lowering or changing the angle of the transducer. NOTE Periodically wash the transducer's face with soap and water to remove any oil film. Oil and dirt on the face will reduce the sensitivity or may even prevent operation. CAUTION! MAKE CERTAIN TO CLAMP THE TRANSDUCER CABLE TO THE TRANSOM NEAR THE TRANSDUCER. THIS WILL HELP PREVENT THE TRANSDUCER FROM ENTERING THE BOAT IF IT IS KNOCKED OFF AT HIGH SPEED.

The PWR key also controls the lights. Once the it's turned on, press the PWR key to turn the lights on. Press the PWR key again to turn the lights off. To turn the sonar unit off, press and hold the PWR key while a "countdown" appears on the screen. The unit will shut itself off when the countdown reaches zero. Release the PWR key. MENUS The sonar unit uses menus extensively to guide you through the functions and features of the unit. To use the menus, simply press the MENU key. The options on the menus let you to customize the unit to your particular needs and water conditions. Use the up and down arrow keys to move to different menus. The left and right arrow keys select and adjust menu items. If you ever get lost in a menu, simply press the EXIT key. This clears the menus from the screen. DUAL FREQUENCY OPERATION This unit has the capability to operate at both 192 kHz and 50 kHz when the optional SAM-50HPD is attached. When the sonar unit is turned on for the first time, 192 kHz only is in use. To activate the 50 kHz SAM, press the MENU key, then press the up or down arrow keys until the "CHART SETUP" menu appears. Press the right arrow key. The screen shown at right appears. Now highlight the "CHART FREQ" label at the bottom of the screen. Use the left or right arrow keys to switch to the desired operating frequency, then press the EXIT to erase this menu.
When the single frequency mode is enabled, as shown at right, adjusting sensitivity or grayline is straightforward. Simply press the MENU key, then press the up or down arrow keys until the desired menu appears, then make the adjustment using the left or right arrow keys.
However, you can adjust some features separately when you're using both 50 and 192 kHz. For example, the sensitivity menu shown at right lets you select either the 192 or 50 kHz chart by pressing the appropriate arrow key. To adjust the 192 kHz sensitivity, press the left arrow key. The screen shown below appears.
This is the 192 kHz sensitivity menu. Press the left or right arrow keys to adjust it, then press the EXIT key to erase the menu. See page 27 for more information on sensitivity adjustment.
MODES This unit has five different modes: FASTRAK, digital/chart, split-chart, full chart, and window groups. Each of these modes also has multiple options. To select a different mode, first press the MODE key. A screen similar to the one at right appears. Press the up or down arrow key to select the desired mode, then press the left or right arrow key to select an option from that mode, if necessary. Press the EXIT key to erase the menu. FASTRAK This feature converts all echoes to short horizontal lines on the displays far right side. The graph continues to operate normally. FASTRAK gives you a rapid update of conditions directly under the boat. This makes it useful for ice fishing, or when youre fishing at anchor. Since the unit is not moving, fish signals are long, drawn out lines on a normal chart display. FASTRAK converts the graph to a vertical bar graph that, with practice, makes a useful addition to fishing at a stationary location. Full Chart This is the default mode used when the unit is first turned on. 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. "192" next to the digital depth shows the frequency of the digital sonar. In this case, it's operating at 192 kHz. The word "AUTO" at the screen's top center shows that the sonar is in the automatic mode, freeing you from sensitivity, range, and noise rejection adjustments.The "192 KHZ" at the bottom of the screen shows that this chart is operating at 192 kHz. You can switch the full chart between 192 and 50 kHz.
Split Chart The split chart normally 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 the split 192 kHz example screen shown at right, the zoom range is 2X, or two times the right side's view. By pressing the ZOUT and ZIN keys, you can change the left side's zoom from 2X to 4X and back. You can switch the split chart screen from 192 kHz to split 50 kHz to 192/50 or 50/192. Digital/Chart The digital/chart shows the chart on the right side of the screen. The left side has four digital boxes containing the water depth at the top of the screen, boat speed, distance travelled (log), and surface water temperature. At the bottom of the screen is a temperature graph. (Note: Speed, distance, and temperature displays require a speed/temperature sensor(s) which must be purchased separately.) Windows The windows feature lets you use different displays for your own fishing or boating situations. It also gives you 8 different display screens in the window groups alone. The screens available in the windows mode are divided into two or more windows per screen. Each screen of windows is called a group. Group A as shown at right has the digital depth display in one window, battery voltage in another, water temperature, speed, and distance travelled. To use the windows feature, first press the MODE key. A screen similar to the one shown at right appears. Highlight the "Group" menu at the bottom of the screen. Now press
the left or right arrow keys to sequence through the available groups. When the desired group appears, press the EXIT key to erase the modes menu. Reprogram Windows Groups You can customize the window groups to meet your own fishing or boating situations. This unit gives you eight different windows that can be rearranged into many combinations. To reprogram a group, first go to the "System Setup" menu as shown at right. Next, highlight the "Reprogram Groups" label and press the right arrow key. A screen similar to the one shown at right appears. Press the right or left arrow keys to select the window group that you want reprogrammed. We'll customize group "H" in this example. Once the desired window group shows, press the up arrow key to reprogram it. The screen shown at the bottom of this page appears. The 1/4 chart appears in the upper right corner. Press the left or right arrow keys to view the available windows. When the desired window appears, press the up arrow key to select it. The unit adds this window to the selected group, then returns to this screen so you can select the next window. Once you've selected all of the windows for your group, it returns to normal operation with the customized screen showing. In this example, we changed group "H" to the one shown at the top of the next page.
Reset Window Groups To return all groups to the factory settings, use the "Preset Options" on the "System Setup" menu. To return only one group to its factory setting, select "reprogram groups" from the "System Setup" menu. The screen shown below right appears.
Press the left or right arrow key until the desired window group that you want to reset appears. When it appears, simply press the down arrow key and the unit will reset only that group. Press the EXIT key to erase the menu.
AUTOMATIC When the sonar unit is first turned on, the Automatic feature is enabled. This is indicated by the word AUTO at the top of the screen. The Automatic feature adjusts the sensitivity and range so the bottom signal is displayed in the lower half of the screen at all times. To turn Automatic off, first press the MENU key, then press the up or down arrow keys until the "AUTO" menu appears. Press the left arrow key to switch to the manual mode. The letters Man appear at the top of the screen, indicating the unit is in the manual mode. To turn Automatic on, repeat the above steps to get the auto menu, then press the right arrow key.
SENSITIVITY The sensitivity controls the ability of the unit to pick up echoes. A low sensitivity level excludes much of the bottom information, fish signals, and other target information. High sensitivity levels enables you to see this detail, but it can also clutter the screen with many undesired signals. Typically, the best sensitivity level shows a good solid bottom signal with Grayline and some surface clutter. When the it's in the Automatic mode, the sensitivity is automatically adjusted to keep a solid bottom signal displayed, plus a little more. This gives it the capability to show fish and other detail. However, situations occur where it becomes necessary to increase or decrease the sensitivity. This typically happens when you wish to see more detail, so an increase in sensitivity is indicated. The procedure to adjust it is the same whether the unit is in the automatic or manual mode. To adjust the sensitivity, press the MENU key, then press the up or down arrow keys until the "SENS" menu appears as shown above. The sensitivity menu has left and right arrows, plus a horizontal bar graph. The graph gives a visual indication of the sensitivity level. The number to the right of the bar graph shows the percentage of sensitivity in use. To increase the sensitivity level, press the right arrow key. As you press the key, the menus bar graph will grow wider and the percentage will increase in value. You can also see the difference on the chart record as it scrolls. When the sensitivity is at the desired level, release the key. To decrease the sensitivity level, press the left arrow key. The bar graph and percentage will decrease. When the sensitivity is at the desired level, release the key. When you reach either the maximum or minimum limit, a tone sounds. To erase the menu, press the EXIT key.
down arrow keys until the GRAYLINE menu appears. A screen similar to the one at right appears. Press the left arrow key to decrease the gray level or the right arrow key to increase it. The percentage of GRAYLINE in use changes as the arrow keys are pressed. The bar chart also gives a graphical indication of the GRAYLINE level. You can see the change on the screen (both on the menu and on the chart record) as you press the keys. After youve finished, press the EXIT key to erase the menu. CHART SPEED The rate echoes scroll across the screen is called the chart speed. Its adjustable by first pressing the menu key, then pressing the up or down arrow keys until the "CHT SPD" (chart speed) menu appears as shown below left. 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. The bar chart also gives a graphical indication of the chart speed. You can see the change on the screen (both on the menu and on the chart record) as you press the keys. After youve made the adjustment, press the EXIT key to erase the menu.

To stop the chart, press the menu key, then press the up or down arrow keys until the "CHART" menu appears as shown above right. Press the left arrow key to stop the chart. To start the chart again, press the right arrow key.
FISH ID The Fish ID feature identifies targets that meet certain conditions as fish. The microcomputer analyses all echoes and eliminates surface clutter, thermoclines, and other signals that are undesirable. In most instances, remaining targets are fish. The Fish ID feature displays symbols on the screen in place of the actual fish echoes. There are four fish symbol sizes: tiny, small, medium, and large. These are used to designate the relative size between targets. In other words, it displays a small fish symbol when it thinks a target is a small fish, a medium fish symbol on a larger target, etc. The microcomputer is sophisticated, but it can be fooled. It can't distinguish between fish and other suspended objects such as trotlines, turtles, submerged floats, air bubbles, etc. Individual tree limbs extending outwards from a group of limbs is the hardest object for the Fish ID feature to distinguish from fish. You may see Fish ID symbols on the screen when actually, there are no fish. Practice with the unit in both the Fish ID mode and without to become more familiar with the Fish ID feature. When the unit is turned on for the first time, the Fish ID feature is automatically turned off. To turn the Fish ID feature on, press the menu key, then press the arrow keys until the FISH ID menu appears. Press the right arrow key to turn the fish ID feature on. To turn the Fish ID feature off again, repeat the above steps, but press the left arrow key until "OFF" is highlighted. Any targets the microcomputer determines are fish will be displayed as fish symbols. Remember, the Fish ID feature cant be used when the unit is in the manual mode. If you turn the Fish ID feature on when the unit is in manual, the microcomputer will turn the automatic feature on. If you turn automatic off when the Fish ID feature is on, the Fish ID feature will be turned off also. 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 ID feature is on.
SYSTEM SETUP The following features are available through the "System Setup" menu. To access this menu, press the MENU key, then press the up or down arrow keys until the "System Setup" menu appears. Press the right arrow key. The screen shown at right appears. Audio/Display You can adjust the display's contrast, turn the speaker off or on, and adjust the light intensity using this menu. To do this, highlight the "Audio/Display" label on the system setup menu, then press the right arrow key. The screen at right appears. To adjust the contrast, highlight the "Contrast" menu, then use the left or right arrow key to change it. Look at the pattern at the bottom of this screen to adjust the contrast for the best sharpness. To turn the speaker off, highlight the "Speaker" label, then press the left arrow key to turn it off. To adjust the backlight, highlight the "Backlight" label, then use the left and right arrow keys to change the light's intensity. System Information This screen shows some basic data about the sonar unit. To view this, highlight the "System Info" label on the System Setup menu, then press the right arrow key. The system info screen appears. To erase this screen, press the EXIT key. The unit returns to the System Setup menu. Units of Measure The sonar normally shows the depth in feet, speed in statute miles per hour, distance in statute miles, and temperature in degrees Fahrenheit. You can change any of these settings using the units of measure menu. To do this, highlight the "Units of Measure" label on the System Setup menu, then press the right arrow key. The screen at the top of the next page appears. Highlight the item you want to change, then press the right or left arrow key to change it. To erase this screen, press the EXIT key.
Temperature Graph Some of the screens have a temperature graph, as shown at right. Normally, the temperature graph has a 2 range. On the screen shown at right, the temperature graph has a range from 71 to 73. You can change this range to 4 or 10 using the "Temp Graph Scale" label on the Units of Measure menu. Highlight that label, then press the right arrow key until the desired temperature graph range is highlighted. Press the EXIT key to erase the menu. Reset Distance Log If you have a speed sensor attached, the unit starts counting the distance you've travelled each time you turn it on. You can reset this distance to zero by turning the unit off and on again, however, it's easier to highlight the "Reset Distance Log" label on the System Setup menu, then press the right arrow key. This resets the log and keeps you in the System Setup menu. To erase this menu, press the EXIT key. Preset Options The unit "remembers" all settings such as units of measure, auto/manual, sensitivity, even when power is removed from the unit. To return the unit to the factory settings, highlight the "Preset Options" label on the "System Setup" menu, then press the right arrow key. It returns to the full chart screen with all settings returned to their factory values.
Keel Offset The sonar 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 sonar reports 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 "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 in the upper right corner. In this example, we need to change the keel offset so that the sonar 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 "Adj Keel" 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, we'll 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 doesn't 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. Simulator This unit has a simulator built in that lets you use it as if you are on the water. All features and functions of the unit are usable. A message appears occasionally to remind you that the simulator is on. To use the simulator, press the MENU key, then press the up or down arrow keys until the "System Setup" menu appears. When it does, press the right arrow key. Now press the up or down arrow keys until the "Simulator" label is highlighted. Finally, press the right arrow key. The unit returns with both simulated digital data and chart echoes.
If your unit is not working, or if you need technical help, please use the following troubleshooting section before contacting the factory customer service department. It may save you the trouble of returning your unit. Unit wont turn on: 1. Check the power cables connection at the unit. Also check the wiring. 2. Make certain 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 units power connector. It should be at least 11 volts. If it isnt, 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 boats 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 units 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 both the transducer and power connectors. Make certain both are securely plugged in to the unit. Weak bottom echo, digital readings erratic, or no fish signals: 1. Make certain 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. Do NOT use RTV silicone rubber adhesive or Marinetex 2. Electrical noise from the boats 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 sonars ability to find the bottom. If the sonar cant find the bottom signal while its in the automatic mode, the digital will flash continuously. It may change the range to limits far greater than the water you are in. If this happens, place the unit in the manual mode, then change the range to a realistic one, (for example, 0-100 feet) and increase the sensitivity. As you move into shallower water, a bottom signal should appear. 4. Check the battery voltage. If the voltage drops, the units transmitter power also drops, reducing its ability to find the bottom or targets. Bottom echo disappears at high speeds or erratic digital reading or weak bottom echo while boat is moving 1. The transducer may be in turbulent water. It must be mounted in a smooth flow of water in order for the sonar to work at all boat speeds. Air bubbles in the water disrupt the sonar signals, interfering with its ability to find the bottom or other targets. The technical term for this is Cavitation. 2. Electrical noise from the boats 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. Try using resistor spark plugs or routing the sonar units power and transducer cables away from other electrical wiring on the boat. No fish arches when the Fish ID feature is off: 1. Make certain transducer is pointing straight down. This is the most common problem if a partial arch is displayed. 2. The sensitivity may not be high enough. In order for the unit to display a fish arch, it has to be able to receive the fishs echo from the time it enters the cone until it leaves. If the sensitivity is not high enough, the unit shows the fish only when it is in the center of the cone. 3. Use the Zoom feature. It is much easier to display fish arches when zoomed in on a small range of water than a large one. For example, you will have much better luck seeing fish arches with a 30 to 60 foot range than a 0 to 60 foot range. This enlarges the targets, allowing the display to show much more detail. 4. The boat must be moving at a slow trolling speed to see fish arches. If the boat is motionless, fish stay in the cone, showing on the screen as straight horizontal lines.
NOISE A major cause of sonar problems is electrical noise. This usually appears on the sonars display as random patterns of dots or lines. In severe cases, it can completely cover the screen with black dots, or cause the unit operate erratically, or not at all. To eliminate or minimize the effects of electrical noise, first try to determine the cause. With the boat at rest in the water, the first thing you should do is turn all electrical equipment on the boat off. Make certain the engine is off, also. Turn the sonar unit on, then turn off ASP (Advanced Signal Processing). There should be a steady bottom signal on the display. Now turn on each piece of electrical equipment on the boat and view the effect on the sonars display. For example, turn on the bilge pump and view the sonar display for noise. If no noise is present, turn the pump off, then turn on the VHF radio and transmit. Keep doing this until all electrical equipment has been turned on, their effect on the sonar display noted, then turned off. If you find noise interference from an electrical instrument, trolling motor, pump, or radio, try to isolate the problem. You can usually reroute the sonar units power cable and transducer cable away from the wiring that is causing the interference. VHF radio antenna cables radiate noise when transmitting, so be certain to keep the sonars wires away from it. You may need to route the sonar units power cable directly to the battery to isolate it from other wiring on the boat. If no noise displays on the sonar unit from electrical equipment, then make certain everything except the sonar unit is turned off, then start the engine. Increase the RPM with the gearshift in neutral. If noise appears on the display, the problem could be one of three things; spark plugs, alternator, or tachometer wiring. Try using resistor spark plugs, alternator filters, or routing the sonar units power cable away from engine wiring. Again, routing the power cable directly to the battery helps eliminate noise problems. Make certain to use the in-line fuse supplied with the unit when wiring the power cable to the battery. When no noise appears on the sonar unit after all of the above tests, then the noise source is probably cavitation. Many novices or persons with limited experience make hasty sonar installations which function perfectly in shallow water, or when the boat is at rest. In nearly all cases, the cause of the malfunction will be the location and/or angle of the transducer. The face of the transducer must be placed in a location that has a smooth flow of water at all boat speeds. Read the transducer installation section in this manual for the best mounting position.
