Key Functions
Your 300 Series™ Fishing System user interface consists of a set of easy-to-use keys that
work with various on-screen views and menus to give you flexibility and control over
your fishing experience.
POWER/LIGHT Key
The POWER/LIGHT key is used to turn the 300 Series™ Fishing System on
and off, and also to adjust the backlight and contrast of the display. Press
the POWER/LIGHT key to turn the unit on. The Title screen is then
displayed until the 300 Series™ Fishing System begins sonar operation.
To adjust the backlight, or to adjust the display background
color, press the LIGHT key to access the Light and Background
menu. Use the 4-WAY Cursor key to select Light or Background
and then use the LEFT or RIGHT Cursor key to change the
settings. Press EXIT to exit the Light and Background 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 300 Series™
Fishing System should always be turned off using the POWER/LIGHT key. This will
ensure that shutdown occurs properly and any menu settings will be saved.

key to advance to the next view. Repeatedly pressing VIEW cycles
through all views available. Views can be hidden to optimize the system
