1.3DSC Operational Overview

Digital Selective Calling (DSC) is the global calling system adopted by the ITU-R and IMO for selective calling of coast station and ship radio stations. The DSC system is used for both safety and routine calling. The GMDSS requires the use of DSC for distress alerting and safety calls.

1.3.1LED warnings

The LED below the DISTRESS key lights continuously when the distress signal is transmitted.

The ALARM LED blinks in red (and alarm sounds) when a distress or urgent message is received. The LED can be extinguished and alarm silenced by pressing the CANCEL key.

The ALARM LED blinks in green (and alarm sounds) when a message other than distress or urgent is received. Alarm is automatically silenced two minutes after message is received.
