The Menu System
A simple menu system allows you to access your FF918 adjustable settings. To
activate the menu system, press the POWER-MENU key. Press the POWER-MENU
key repeatedly to display the FF918 menu settings, one at a time. When a menu
settings is on the display, use the UP and DOWN arrow keys to adjust the menu
setting. Menus settings are removed from the screen automatically after several
seconds. In normal operating mode, most menu settings saved to memory will not
return to their default values when the unit is turned off. See individual menu choices
for more information.
NOTE:
Each time the POWER-MENU key is pressed, the backlight momentarily
illuminates for easy viewing at night. Adjust the LIGHT menu setting to keep the
backlight on.
Sensitivity
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 –9).
