DSC call menu | RS20S User Guide
The Distress Call is automatically re-sent every 3.5 to 4.5 minutes
until a distress acknowledgement is received.
Alternatively the operator can select:
RESEND (under OPTION - access by pressing the Menu/DSC button)
used to immediately resend the Distress Call
PAUSE (under OPTION - access by pressing the Menu/DSC button)
used to pause the automatic Distress Call resend timer
CANCEL (press ‘X’ button) to cancel the Distress Call
If a distress cancel is sent, the display shows PTT --> REASON,
prompting the operator to state the reason for the cancellation.
After a DISTRESS ACK is received, the alert should be silenced, and
the reason for distress should be clearly stated, pressing the ‘PTT’ on
the MIC and talking.
The following information (if available) is contained in the Distress
Call:
• Nature Of Distress (if selected)
• Position information (the latest GPS or manual input position is held
for 23.5 hours, or until the power is turned OFF).

group list, by entering a new GCID, or by selecting a group from the
RECENT list.
