6.2 Receiving a Distress Call (DISTRESS!)

1. An alert sounds when a distress call

(DISTRESS!) is received. Press any
key to cancel the alert. You do not need
to send an acknowledgement.

2. The radio automatically selects CH16 and displays the details of the distress call on the

screen. Press PTT to establish voice contact.

The details are displayed over two screens that alternate every 1.5 seconds; the fi rst screen
shows the user MMSID and nature of the emergency (if specifi ed), the second screen shows
the time and the location (if specifi ed). If the location and time are not specifi ed, these are
replaced with sequences of 9s and 8s respectively.

The VHF7200 is capable of receiving enhanced LL position data if the vessel transmitting the
Distress Call is sending this. This provides the position of the distressed vessel to within 20m
(60ft).

6.3 Distress Acknowledgement (DISTRESS ACK) or Relay

An alert sounds when a Distress Relay (DISTRESS RELAY) is
received. Press any key to cancel the alert.

Try to make voice contact with the calling vessel. Maintain a listening
watch on CH16 and standby to lend assistance.

For a Distress Acknowledgement (DISTRESS ACK) sent from the

Coast Guard, your radio automatically cancels Distress Mode transmissions and CH16 appears.
Press PTT to establish voice contact with the Coast Guard.

The Coast Guard is the only agency allowed to send a Distress Acknowledgement (DISTRESS
ACK).
