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 rst screen
shows the user MMSID and nature of the emergency (if specied), the second screen shows
the time and the location (if specied). If the location and time are not specied, these are
replaced with sequences of 9s and 8s respectively.
The VHF7100 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 20 m (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).
