Customer Service Department; phone numbers are inside the manual's back cover. Installation Preparations You can install the sonar system in some other order if you prefer, but we recommend this installation sequence: Caution: You should read over this entire installation section before drilling any holes in your vessel! 1.
3. Determine the location of your battery or other power connection, along with the power cable route. 4. Install the transducer and route the transducer cable to the sonar unit. 5. Install the power cable and route it to the sonar unit.
If the transducer is not placed in a smooth flow of water, interference caused by bubbles and turbulence will show on the sonar's display in the form of random lines or dots whenever the boat is moving.
usually give you the best combination of smooth water flow and protection from bangs and bumps. Transducer centerline Align transducer centerline with hull bottom. However, there are times when you may need to adjust the transducer slightly higher or lower. (The slots in the mounting brackets allow you to loosen the screws and slide the transducer up or down.) If you frequently lose bottom signal lock while running at high speed, the transducer may be coming out of the water as you cross waves or...
parts first, place the transducer's bracket against the transom and see if you can move the transducer so that it's parallel with the ground. 1. Assembling the bracket. Press the two small plastic ratchets into the sides of the metal bracket as shown in the following illustration. Notice there are letters molded into each ratchet.
3. Assembling the transducer. position for the ratchets, assemble the transducer as shown in the following figure. Don't tighten the lock nut at this time. Assemble transducer and bracket. 4. Drilling mounting holes. Hold the transducer and bracket assembly against the transom. The transducer should be roughly parallel to the ground.
Align transducer centerline with hull bottom and attach to transom. 6. Route the transducer cable through or over the transom to the sonar unit. Make sure to leave some slack in the cable at the transducer. If possible, route the transducer cable away from other wiring on the boat.
(not included) to attach the transducer cable to the trolling motor shaft. Make sure there is enough slack in the cable for the motor to turn freely. Route the cable to the sonar unit and the transducer is ready for use.
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.
ASP.) Don't touch the controls once they've 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.
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. Epoxy transducer to hull. Transducer location...
To unit Power and transducer connections for the X47 and X47EX sonar units (direct battery connection shown). If possible, keep the power cable away from other boat wiring, especially the engine's wires.
You can install the sonar unit on the top of a dash with the supplied bracket. It can also be installed in the dash with an optional dash- mounting kit (FM-5 mount kit for X47EX, FM-6 mount kit for X47). In-Dash Installation For the X47EX The following figure shows dimensions for in-dash mounting an X47EX.
For the X47 The X47 can be mounted in-dash using the removable scaled template inside the back cover of this manual (page 43). The FM-6 mount kit includes the necessary materials, but the instructions only appear here in this manual.

The power pack and portable or floating transducers expand the uses for your sonar. You can use your X47 sonar unit on your boat or take it to the dock, on a float tube, on an ice fishing trip or use it as a second sonar in a friend's boat.
"D" cell battery Install batteries in power case battery adapter. PPP-13 shown. Turn the sonar unit on. If it doesn't work, make sure the battery terminals are making good contact against the battery contacts. Also...
In cold weather the efficiency of dry cell batteries drops with the temperature. We find it a good idea to have the sonar unit good and warm along with the batteries before we leave home.
Moisten the cup, then press it onto the hull as firmly as possible. Tie the nylon cord to the boat and route the transducer cable to the sonar unit. Your portable sonar is now ready for use.
The unit sounds a tone when you press any key. This tells you the unit has accepted a command. Numbers in the following photos correspond to key explanations in the following pages: X47 and X47EX Sonars, front view, each 1. PWR/CLEAR (power and clear) This key appears in the manual text simply as turn the unit on and off.

When you Zoom while the unit is in manual depth Range Zoom mode, you can select one of 13 pre-set Zoom Sizes. This lets you enlarge some other particular segment of the water column. To do this, first make sure the depth Range Zoom is in manual mode. (See previous instructions for Depth Range Zoom.) Next, press the key until the MENU...
In your unit, auto mode will let you increase sensitivity to 100 percent, but the unit will limit your minimum setting. This prevents you from turning sensitivity down too low to allow automatic bottom tracking. When you change the setting with auto turned on, the unit will continue to track the bottom and make minor adjustments to the sensitivity level, with a bias toward the setting you selected.
Since Grayline shows the difference between strong and weak signals, adjusting the sensitivity may also require a different Grayline level. The level chosen by the sonar unit at power on is usually adequate for most conditions. Experiment with your unit to find the Grayline setting that's best for you.
Thin or no Grayline At left, little Grayline indicates a soft bottom, probably sand or mud. At right, the wider Grayline indicates a harder, rocky bottom. Press UP ARROW decrease it. The percentage of Grayline in use shows in this menu. Echoes scrolling onto the screen will also show the effects of the Grayline change.
Fish I.D. is an easier way for a sonar novice to recognize a fishy signal return when he sees it. However, locating fish by symbol only has some limitations. Your sonar unit's 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.
50 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.
ASP 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.
bottom goes shallower than the alarm's setting. The deep alarm sounds a tone when the bottom goes deeper than its setting. Both alarms adjust the same way, although through different menus. Shallow Alarm To set the shallow alarm depth, press repeatedly until Press UP ARROW...
DISPLAY CONTRAST The unit’s display contrast is adjustable to suit different lighting conditions. This will help you see the screen from different angles or at various times of the day. The default setting is min (minimum) percent. To adjust the contrast, press menu appears.
SIMULATOR This unit has a built-in simulator that shows a simulated bottom signal with fish signals. This lets you practice with the unit as if you were on the water; all features and functions of the unit are usable. A message appears occasionally to remind you that the simulator is on.
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.
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. If the sonar can't find the bottom signal while it's in the automatic mode, the digital sonar display will flash continuously.
With the boat at rest in the water, the first thing you should do is turn all electrical equipment on the boat off. Make sure the engine is also off. Turn your sonar on, then turn off Noise Reject [also known as the ASP feature (Advanced Signal Processing)].
