About the 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 rst call in the call list.
Viewing the DSC List
Your chartplotter must be connected to a VHF radio that supports DSC in order to view the DSC list.
