11.3 DISTRESS ALERT
The GX1100S is capable of transmitting and receiving DSC Distress messages
to all DSC radios. The GX1100S 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 GX1100S
will beep 10 minutes after the radio is turned on. After that the GX1100S
will beep every 4 hours alerting to connect a GPS.
