GAIN CONTROL

The knob located at the top of the control panel is the gain control.

This controls the amount of signal that you see on the display. A gain

setting of zero will display a minimum amount of signal while a gain set-

ting of ten will show the maximum amount. Different conditions will

require different gain settings. Deeper water will require higher gain

than shallow water. A weedy bottom will demand a lower gain setting

than a clean bottom. Keep the gain level low. Too much gain can "wash

out" the targets that you want to see. Generally, it is a good idea to set

the gain at an appropriate level and leave it there. Only change the gain

level if the water depth or conditions change.

INTERFERENCE REJECTION*

The yellow button in the middle of the panel controls the Interference

Rejection feature. The red LED to the upper left of the I.R. button tells

you if the rejection circuitry is on. The I.R. feature has eight steps of rejec-

tion to let you eliminate unwanted interference from another nearby

depth finder. When you turn on the FL-8SLT on, the I.R. automatically

comes on to the first step. If necessary, press the I.R. button repeatedly

until the interference is eliminated. You can press the button seven times

before you get back to the first step again. Turning the unit off and then

on again will also reset the I.R. back to the first step. To turn the I.R. fea-

ture off press the Gain control knob. The red LED will also go off.

TIP - If running two SLTs, it is best to turn the I.R. off on one unit

and then eliminate the interference on the other unit.
