Garmin gpsmap 178, 178c Manuale Utente

The Garmin GPSMAP 178/178C Sounder is a powerful electronic navigation system that provides 

detailed map coverage and convenient control of many advanced features right from the screen display. 
This tour is designed to take you through the basic pages and functions of the system using the simulator 
mode. Once you’re familiar with the main pages and functions of the unit, refer to the reference section 
for instructions on performing specific tasks and functions.

The Getting Started Tour assumes that the receiver has been properly installed and initialized, and 

you have not changed any of the default unit settings. If you have changed any settings (position  
formats, units of measure, etc.), the descriptions and pictures in the tour may not match your  
configuration.

1.  Press and hold the POWER key until the power tone sounds, then release the POWER key. The Warn-

ing Page appears while the unit conducts a self-test.

2.   Once the self-test is complete, press the 

ENTER/MARK key to agree and acknowledge the warning.

The GPS Information Page appears as the receiver begins acquiring satellites. From this or any other 

page, you may also adjust the screen backlighting.

The GPSMAP 178/178C’s adjustable screen backlighting is controlled with the POWER key. The 

backlight can cycle through minimum, user-defined, and maximum backlight levels by repeatedly press-
ing the POWER key.

1.  Press POWER and the Light/Contrast window appears. 
2.   Press POWER again and the user-defined level of backlighting activates. You may adjust this level by 

pressing UP or DOWN on the ARROW KEYPAD. If you press POWER one more time, the backlight-
ing is at the minimum setting. Press LEFT (brighter) or RIGHT (darker) to adjust the contrast.

3.   Press ENTER or QUIT when done.

A full-screen GPS Information pop-up page is displayed 
after you press the ENTER key to acknowledge the  
Warning Page. The pop-up page goes away after the unit 
gets a position fix or you press either ENTER or QUIT.
