7.10.2 SENDING A DISTRESS CALL
The distress call automatically includes the vessel’s DSC MMSI and Lat/Lon
position. The vessel’s position will only be transmitted if the transceiver is
properly connected to an operating GPS receiver with NMEA output.
1. Lift the red DISTRESS rubber cover on the right side of the transceiver
and press the [DISTRESS] key. “DSC DISTRESS” will appear on the
LCD.
2. Press and hold in the [DISTRESS] key for 3 seconds. The LCD will count
down (3s, 2s, 1s), and afterwards the HX600S will transmit the DSC Dis-
tress Call on channel 70.
3. When the distress signal is being sent, “
” icon
will appear on the LCD. After the message has
been sent, the Distress Alarm will sound.
4. The transceiver received for a transmission CH16 until an acknowledg-
ment signal is received.
5. If no acknowledgment is received, the distress call is repeated in three
minute intervals until an acknowledgment is received.
6. To cancel the distress call alarm, press the [16/9] key.
7. To send the CANCEL call:
Press the [DISTRESS] key, then press the [S] or [T] key until “CAN-
CEL” is shown on the LCD. Press the [DISTRESS] key.
NOTE: When a GPS receiver with NMEA output is connected via the CD-33
Charger Cradle, the vessel’s position is automatically transmitted with the
distress call. The HX600S will remember the position input from the GPS
until the radio is turned off.
