Garmin gpsmap 278 Manuale Utente

Before you turn on the GPSMAP 278, be sure the antenna is rotated 

up as shown on page 

, and it has a clear and unobstructed view of 

the sky to receive satellite signals. 
The first time you turn on your GPSMAP 278, the GPS receiver 

must collect satellite data and establish its current location. To 

ensure proper initialization, the GPSMAP 278 is shipped from the 

factory in AutoLocate mode, which allows the receiver to “find 

itself” anywhere in the world.
