DIGITAL SELECTIVE CALLING FEATURES (DSC)

WHAT IS DSC?
Digital Selective Calling (DSC) is a standard that allows you to call other ships using their unique
identification code (the Maritime Mobile Service Identity or MMSI number), just like you would call a
phone number. To call another station, just enter that station' s MMSI number and choose the voice chan-
nel you want to talk on. The radio uses channel 70 to transmit your MMSI number to the other station

cally switch to the requested voice channel so you can talk to the other station.
DSC provides a system for automated distress calls. At the touch of a key, the radio can transmit your
