4.1Sending Distress Alert

GMDSS ships carry a DSC terminal with which to transmit the distress alert in the event of a life-endangering situation. A coast station receives the distress alert and sends the distress alert acknowledge call to the ship in distress. Then, voice or telex communications between the ship in distress and coast station begins. Transmission of the distress alert and receiving of the distress alert acknowledgement are completely automatic – simply press the DISTRESS button to initiate the sequence. Note that the distress can also be transmitted from the Distress Alert Unit IC-302.

There are four types of sending distress alert; MULTI, AUTO, SELECT and 2-16MHz. MULTI is used normally. When changing to other method, see step 15 on paragraph 4.1.2.
