The Adjustment Menu allows direct access to the settings and 

features most commonly used on the Sonar page. There are 10 main 

adjustment options available: Range, Zoom, View, Gain, Target 

Level, Whiteline, Frequency, Depth Line, Noise Reject, and 

Scroll. All adjustments may be made by using the ARROW keys 

and ENTER key. The currently selected option will appear in the 

upper left of the display with up and down arrows on either side of 

the name.
