Garmin 278 Manual De Usuario

To receive distress calls or position reports, you must have a  

DSC-equipped chartplotter as well as a VHF radio with DSC 

support. During normal, non-emergency position report 

communication, Channel 70 (156.525 MHz) has been set aside as 

the VHF/DSC digital call channel. 
For a distress call, press the MayDay button on the VHF radio. The 

call transmits on an emergency channel with the MMSI number 

attached to the call, if the receiver has DSC support. Any DSC-

equipped mariner (on sea or land) within range can receive the call.
When the GPSMAP 278 is connected to a VHF with DSC support, 

the GPSMAP 278 shows a call list, log, and a directory. Basic wiring 

is required for the Garmin unit and VHF radio to send and receive 

NMEA data from each other.

Hereby, Garmin, declares that this GPSMAP 278 is in compliance 

with the essential requirements and other relevant provisions of 

Directive 1999/5/EC.
To view the full Declaration of Conformity, see the Garmin Web site
