A valid USER MMSI must be entered into this radio before these DSC functions can be 
used. See section 5-1.

DSC (Digital Selective Calling) is a semi-automated method of establishing VHF, MF, and HF 
radio calls. It has been designated as an international standard by the IMO (International Mari-
time Organization) and is part of the GMDSS (Global Maritime Distress and Safety System). 

Currently, you are required to monitor Distress Channel 16, but DSC will eventually replace 
listening watches on distress frequencies and will be used to broadcast routine and urgent 
maritime safety information. 

DSC enables you to send and receive calls from any vessel or coast station that is equipped 
with DSC functionality and within geographic range. Calls can be categorised as distress, 
urgency, safety, or routine, and DSC selects a working channel automatically. 

You can call any other person that has another DSC equipped radio.

Press CALL MENU to access the following DSC CALL menu options – select LAST CALL to 
quickly call back the person who called you.

Note that only three DSC CALL menu options can be shown on the LCD at any one time. 

Press + or – on the microphone OR turn the Channel Select knob on the base station to scroll 
up or down through the menu until the cursor is positioned at the desired option. Press ENT 
(the center of the Channel Select knob) to display that option.
