DSC Distress Calls
When you make a DSC 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 have manually entered your position information with the time, that 
data is transmitted with the call. For information on manually updating your position 
.
NOTE: Familiarize yourself with the standard distress-call format and protocol to ensure 
that your calls are clear and effective.
Sending an Undesignated Distress Call
When you send an undesignated distress call, the nature of your emergency is not 
transmitted to the receiving stations. Sending an undesignated distress call is a shorter and 
quicker procedure that can save you time during an emergency.
1.  Lift the spring-loaded door, and press and hold the 
DISTRESS
 key for at least three 
seconds. The transceiver beeps, and the screen displays “DISTRESS CALL COUNTING 
DOWN”. The channel pane counts down the seconds from 3 to 1.
