Press the POWER-MENU key until BRIGHTNESS appears. Use the backlight for night fishing.
Select either Off, or On to activate the backlight at the desired level.
Press the POWER-MENU key until SENSITIVITY appears. Sensitivity controls how much detail is shown
on the display. Increasing the sensitivity shows more sonar returns from small baitfish and suspended
debris in the water; however, the display may become too cluttered. When operating in very clear water
or greater depths, increased sensitivity shows weaker returns that may be of interest. Decreasing the
sensitivity eliminates the clutter from the display that is sometimes present in murky or muddy water.
If Sensitivity is adjusted too low, the display may not show many sonar returns that could be fish. (1 –10).
