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.
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.
