4.5 Emergency calls (DSC distress/urgency/safety calls)
In emergency, the DSC is available for distress, urgency, or safety calls. For safety and urgency
calls, either individual calls or area calls is selectable for the type of call. For distress alerts,
either sending after entering the nature of distress or frequency, or not entering anything is
available. In both cases, pressing the DISTRESS key is required to send the distress alert.
4.5.1 Safety or urgency calls to an individual station
■ Procedure ■
The procedure to send the safety or urgency
individual call is similar to the routine call except
selecting the call type to SAF/Indv/TEL or
URG/Indv/TEL (instead of TEL, ARQ or FEC also
available) and normally using the distress and
safety frequencies prior to other frequencies.
- Both calls of the safety test and the safety position request are described below.
- When calling a coast station with requesting the working frequency, input “0” in
the Tx and Rx frequency input field to send the own position data.
