If possible, keep the power cable away from other boat wiring, espe- cially the engines wires. This will provide the best isolation from elec- trical noise. The power cable has two wires, red and black. Red is the positive lead, black is negative or ground. Make sure to attach the in- line fuse holder to the red lead as close to the power source as possible

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
4.Drilling mounting holes. Hold the transducer and bracket assembly against the transom. The transducer should be roughly parallel to the ground. The transducers centerline should be in line with the bottom of the hull. Dont let the bracket extend below the hull
5.Attaching transducer to transom. Remove the transducer from the bracket and re-assembleit with the cable passing through the bracket over the bolt as shown in the following figures

Transducer Orientation And Fish Arches
If the arch slopes up – but not back down – then the front of the trans- ducer is too high and needs to be lowered. If only the back half of the arch is printed, then the nose of the transducer is angled too far down and needs to be raised

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

water flow to the speed sensor. Make sure the sensor will remain in the water when the boat is on plane. Also make sure the location doesnt inter- fere with the boats trailer. Typically, the sensor is mounted about one foot to the side of the transoms centerline
Power Connections
If possible, keep the power cable away from other boat wiring, espe- cially the engines wires. This will provide the best isolation from elec- trical noise. The power cable has two wires, red and black. Red is the positive lead, black is negative or ground. Make sure to attach the in- line fuse holder to the red lead as close to the power source as possible
Bracket Installation
After drilling the hole, pass the connectors up through the hole from under the dash. If you wish, you can fill in the hole around the cable with a good marine caulking compound. Some marine dealers stock ca- ble hole covers to conceal the opening
Attach the unit to the bracket by first connecting the power/transducer and accessory cables. Then, hold the sonar unit vertically and slide it onto the bracket from above. The back of the unit should be touching the front of the bracket as you lower it into position. As you push down, the unit will lock into place with a distinct click

Installing the Batteries
Turn the sonar unit on. If it doesnt work, make sure the battery termi- nals are making good contact against the battery contacts. Also check the wiring connections on the battery adapter. The red wire on the power cable should be attached to the red wire on the battery adapter and the power cables black wire should be connected to the black wire on the battery adapter
Portable Transducer Assembly
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

Sonar Menu
The Sonar Menu contains commands for the major sonar features and options. Most of them are described in detail only in the Advanced Sec- tion, but Sensitivity and Auto Sensitivity are important basic functions that are discussed both here and in the Advanced Section. The other So- nar Menu commands include

You can customize how the Sonar Page pictures and other data are dis- played in many ways. Well discuss all of those features and options in the Advanced Section, but to show you how easy the sonar unit is to op- erate, the next two pages contain a simplified, 10-stepquick reference that will cover most fish finding situations. The quick reference de- scribes how your unit will operate with all the sonar features in their automatic modes, which are set at the factory

Troubleshooting
Unit operates only in demo mode
Unit freezes, locks up, or operates erratically
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 trans- ducer, 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 in- formation is inside the back cover. Do NOT use RTV silicone rubber adhesive or any other type of epoxy. The LEI epoxy is specially formu- lated so that it will cure properly for shoot-throughapplications
