DSC Operation

Making a DSC Distress Call

1. Lift the protective tab over DISTRESS then hold down
DISTRESS for about 5 seconds. A screen appears where
you can select a distress type.
2. To send an undesignated distress call, press PUSH/SELECT
to select it. Otherwise, to send a designated distress call,
rotate PUSH/SELECT to select the distress type, then press
PUSH/SELECT to select it. A confirmation screen appears.
If the displayed distress call option is correct and you want to send the distress call,
rotate PUSH/SELECT to select SEND, then press PUSH/SELECT to confirm it.
Otherwise, if the displayed distress call option is not correct, rotate PUSH/SELECT
to select CANCEL, then press PUSH/SELECT to confirm it. Then repeat Steps 1
and 2 to enter the correct distress call option.
The radio checks Channel 70 before sending the distress call
and displays the following screen. To cancel the distress call
while this screen appears, press PUSH/SELECT.
If the channel is busy, the radio waits until the channel clears, then it sends the
distress call and sounds a distress tone. Then, the radio tunes to Channel 16 and
Channel 70 and waits between 3 minutes and 30 seconds (210 seconds) and 4
minutes and 30 seconds (270 seconds) for an acknowledgement signal. The radio
continues to sound the alarm and listen for an acknowledgement signal until it
receives one.

Receiving a DSC Distress Call

If the radio receives a DSC distress call, you see a screen similar
to the following, and the radio sounds a distress tone. If the name
of the vessel sending the distress call is programmed into the
radio, the vessel's name appears. Otherwise, the vessel's MMSI,
position, time, and nature code appear. Rotate PUSH/SELECT
while a distress call is being received to display additional
information about the distress call.
If the sending radio does not send position and nature code
information with its distress call, you see a screen similar to the
following.
