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
>
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.
