Your Fishfinder will start up with the backlight
on and will automatically turn it off to conserve
power. To turn the backlight on for night fishing,
or to adjust the display contrast, press the
POWER/LIGHT key to access the Light and
Contrast menu. Use the 4-WAY Cursor key to
select Light or Contrast and then use the LEFT or RIGHT Cursor key to change
the settings. Press EXIT to exit the Light and Contrast menu.
Press and hold the POWER/LIGHT key for 3 seconds to turn the unit off. A
message will appear telling you how many seconds there are until shutdown
occurs. Your Fishfinder should always be turned off using the POWER/LIGHT
key. This will ensure that shutdown occurs properly and any menu settings will
be saved.

The VIEW key is used to cycle through all available views. Press
the VIEW key to advance to the next view. Repeatedly pressing
VIEW cycles through all views available. Views can be hidden
to optimize the system to your fishing requirements (see Views
Menu Tab).

Nearest Current Station, then use the RIGHT
Cursor key to display the requested information.
