DSC List
The DSC list is a log of the most recent
DSC calls and other DSC contacts you have
entered. The DSC list can contain up to 100
entries. The DSC list shows the most recent
call from a boat. If a second call is received
from the same boat, it replaces the first call
in the call list.
Viewing the DSC List
Before you can view the DSC list, the chart-
plotter must be connected to a VHF radio
that supports DSC.
