TREES IN THE WATER IMPORTANT When installingthe power cable, make certain that the in-line fuse supplied with the unit is attached to the red conductorof the power cable as close to the power source as possible. This will protect both the unit and the power cable in case either is ever shorted. A connector is • suppliedto attach the fuse to the - power cable. The positive conductorin the power cable is the red conductor.

Follow the instructions on the epoxy package and mix it thoroughly.. Apply a small amount on the entire face of the transducer and pour 1/16" thick level into the area contained by the clay dam. Place the transducer into the epoxy by pushing and turning to force all of the air bubbles out from under the transducerface.

Instead, yourboat is now above a mud bottom. Mud absorbs the sound waves. Thrn up the gain.

With the control in the 60 fathom position,the range may be read in fathoms on the outside 0-60 scale, or may be read in feet on the inside 0-360' scale on the faceplate. fish. NOISE SUPPRESS CONTROL The noise suppress control knob can be used to cut down or eliminate false flashes on the dial.
