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)

CANCEL (press X button) to cancel the Distress Call.
If a distress cancel is sent, the display shows PTT --> REASON,

the reason for distress should be clearly stated, pressing the 'PTT' on
the MIC and talking.
