12.3 DISTRESS ALERT
The GX1150 is capable of transmitting and receiving DSC Distress messages
to all DSC radios. The GX1150 may be connected to a GPS to also transmit
the Latitude and Longitude of the vessel.
NOTE
If a GPS with NMEA output is not connected to the radio, the GX1150
will beep 10 minutes after the radio is turned on. After that the GX1150
will beep every 4 hours alerting to connect a GPS.

To be able to transmit a Distress Alert an MMSI number must be pro-
grammed, refer to section “12.2.2 Programming the MMSI.”
In order for your vessels location to be transmitted either connect a GPS to the
GX1150 (refer to section “9.4 ACCESSORY CABLE”) or manually input your posi-
tion (refer to section “12.11 MANUAL INPUTTING OF THE GPS LOCATION”).
