7.3 DSC DISTRESS ALERT

The HX851E is capable of transmitting and receiving DSC Distress messages
to all DSC radios. The HX851E will also send the Latitude and Longitude of the
vessel when the internal GPS has acquires a satellite fix.
7.3.1 TRANSMITTING A DSC DISTRESS ALERT
To be able to transmit a DSC Distress Alert an MMSI number must be
programmed, refer to section "7.2.2 USER MMSI PROGRAMMING". In
order for your ships location to be transmitted, the internal GPS unit
must be activated, refer to "NOTE" on page 25.

of the transceiver and press the [ DISTRESS ] key. The
"DISTRESS ALERT" menu will appear on the display.
2. Press and hold the [ DISTRESS ] key. The radios dis-
play will count down (3-2-1), and afterwards the
HX851E will transmit the DSC Distress Alert on chan-
nel 70. The backlight of the display and keypad flashes
while the radios display counts down. When the Dis-
tress signal is being sent, the TX/BUSY indicator will
grow red.
3. The transceiver "shadow-watches" for a transmission
between Channel 16 and Channel 70 until an acknowl-
edgment signal is received. The display will be shown
in the illustration on the right.
4. If no acknowledgment is received, the distress call is
repeated in 4 minute intervals until an acknowledgment is received.
5. When a DSC Distress acknowledgment is received, a distress alarm sounds
and channel 16 is automatically selected. The display shows the MMSI of
the ship responding to your distress.
RECEIVED ACK: acknowledgment signal is received.
RECEIVED RLY: relay signal is received from another vessel or coast sta-
