NOTE The Distress Alert call can be aborted if the Distress key is

released at any time before the 5 second countdown has ended.

Press On/C to return to normal radio operation.

The Distress Alert call sent includes the vessel’s MMSI, the

nature of the distress as speciﬁed, the time the call was sent

and the current position of the vessel (if the appropriate navi-

gational receiver is connected to the radio, or a manual posi-

tion has been entered - see section 6.3).

will show “Awaiting Acknowledg” until an acknowledgement

is received. The radio will automatically repeat the Alert

edgement is received, or On/C is pressed (it is not recommend-

ed that the Distress Alert is cancelled manually by pressing

On/C unless you are requested to do so by the rescue authori-

ties).
