OPERATION
This figure shows the main controls of the LC-8
DEPTH CONTROL
The two buttons at the top of the control panel set the depth range
when the unit is in Manual Depth Mode. Pressing the SHALLOW
button changes the range to the next shallowest range. Pressing the
DEEP button changes the range to the next deeper range.
GAIN CONTROL
While in Manual Gain Mode, pressing the DEC button decreases
the gain one step. Pressing the INC button increases the gain one step.
There are 8 steps of Gain control. Different conditions will require dif-
ferent gain settings. Deeper water will require higher gain than shal-
low 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.
