Placing an Individual Routine Call
When you connect your Garmin chartplotter to a Garmin VHF 
NMEA 2000-compatible radio, you can use the chartplotter interface 
to set up an individual routine call. When setting up an individual 
routine call from your chartplotter, you can select one of the 
following channels on which you want to communicate. The radio 
transmits this request with your call.
The selection of a DSC channel is limited to those channels that are 
available in all frequency bands: 6, 8, 9, 10, 13, 15, 16, 17, 67, 68, 
69, 71, 72, 73, or 77.
NOTE: The default channel is 72. However, select 
Channel
 to 
select a different channel from the list. If you select a different 
channel, the chartplotter uses that channel for subsequent calls until 
you call using a different channel.
