Distress Calls
When you make a distress call, your call is transmitted to all
DSC-capable radios within receiving range. Your current GPS
position (latitude and longitude) and the current time are
included in the transmission if you have a GPS device
connected to your transceiver. If you manually entered your
position information with the time, that data is transmitted with
the call.
NOTE:
You should familiarize yourself with the standard
distress-call format and protocol to ensure your calls are clear
and effective.
