instructions that come with the battery. To get the most out of it, follow

these simple tips; Charge the battery as soon as possible after each use

or, if it's cold, as soon as it reaches room temperature. Do not overcharge

or under charge the battery. If possible, use a battery charger that has an

automatic shut-off feature. A battery should be stored, fully charged, in

a cool place. Charge it every month or two when in storage to make sure

it maintains a full charge.

Will The FL-18 Read Through The Ice?

The FL-18 will easily read through ice, provided the ice is CLEAR ICE

and not MILKY ICE. Remember, the transducer must have good contact

with the surface of the clear ice. A bottom indication should appear on

the sounders dial at an appropriate depth. The ice surface must be wet;

water works well.

Why Do I Get Interference?

Electrical interference can be caused by other electrical equipment that

put unwanted signals on the power or transducer line. It usually can be

reduced or eliminated by simple fixes such as resistor spark plugs and

wires on the engine or better grounding on the electrical system.

Sometimes, however, there can be equipment problems that need shop

service.

Another kind of interference comes from another depth finder operat-

ing on the same frequency nearby. The FL-18’s interference rejection cir-

cuitry is designed to knock out most or all of this, but sometimes severe

conditions can still cause interference. The two factors that determine if

this happens are: a) the depth of the water and, b) how far apart the two

sounders are placed. If this interference is happening, each of the sounders

will have a non-stop rotating light moving around the dial. One mov-

ing light rotates around the dial clockwise and on the other sounder the

light will rotate in the counter clockwise direction. To eliminate this prob-

lem you can either move the sounders farther apart or shut one off.
