Garmin 276c Guida Utente

Use the Adjustment Menu to access the settings and features most 

commonly used on the Sonar Page. Ten main adjustment options 

are available: Range, Zoom, View, Gain, Target Level, Whiteline, 

Frequency, Depth Line, Noise Reject, and Scroll. The currently 

selected option appears in the upper-left corner. 

Use one of the following methods to select an adjustment option:
•  Press the

ROCKER right or left to scroll through the

adjustment options. When the adjustment option you want

appears, press

ENTER.

•  Press

MENU, highlight Adjustments, and press ENTER.

Use the

ROCKER to highlight the adjustment, and press

ENTER.

After you select an adjustment option, press the ROCKER up or 

down to change the setting.
You can also press MENU and highlight a shortcut setting to 

quickly change to commonly used settings and values.
Press ENTER to accept the new setting (or press QUIT to cancel) 

and return to the Sonar Page. 

Scroll—adjusts the rate that the sonar display scrolls from right to 

left. If you are sitting still or the sonar display is moving too fast, 

slow the scroll rate or pause the scrolling.
Range—sets the display depth range used for viewing. The unit can 

be set to automatically track the bottom or set to a user-specified 

depth range.
Zoom—allows you to select a display zoom scale or to split 

the display. When a scale other than No Zoom is selected, the 

Adjustment Menu shows a new selection labeled View or Span. The 

Zoom function is divided into six levels: 

• 

2X Split—shows two reduced-size sonar pictures at the same 

time. The right half of the screen shows the complete sonar 

picture at its original scale. The left half shows a portion of 

the original picture at 1/2 depth scale.
