Humminbird 755C Marine GPS System User Manual

Key Functions
Your Chartplotter 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.
The POWER/LIGHT key is used to turn the Chartplotter on and off,
and also to adjust the backlight and background color of the
display. Press the POWER/LIGHT key to turn the unit on. The Title
screen is then displayed until the Chartplotter begins operation.
See Powering Up the Unit for a more detailed explanation of the
different modes you can select on power up.
To adjust the backlight, or to adjust the display
background color, press the POWER/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 Chartplotter 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).
