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 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
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.

VIEW Key 

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 

Setup Menu Tab: Select

Views, Advanced

).

Big Digits View

Big Digits View 

provides digital data in a large, easy-to-see format. Depth is always

displayed. Readouts for temperature, speed and Triplog information are displayed
automatically if the appropriate accessory is connected to the system. The Triplog
shows distance traveled, average speed, and time elapsed since the Triplog was last
reset. The digital readouts in the Big Digits View cannot be customized.

Circular Flasher View

Circular Flasher View

displays Real Time Sonar (RTS®) data in the traditional flasher

format.  Depth and temperature are always displayed.  The digital readouts in the
Flasher View cannot be customized.
