3  DSC OVERVIEW 

This type of call is sent by own ship in the event of distress, by using the [DISTRESS] 
button as follows: 
 

1. 

The LED in the [DISTRESS] button initially flashes, and lights when the button is 

pressed more than three seconds. (If the button is pressed less than three seconds, 
the distress alert is not sent. Once the alert is sent it cannot be cancelled.) 

If the distress is accidentally transmitted,
contact the nearest coast station and inform
them of the accidental transmission as
follows:

a) Ship's name
b) Ship's call sign and DSC number
c) Position at time of transmission
d) Time of transmission

 

2. 

The radiotelephone automatically sets the DSC distress frequency and then the 

equipment transmits the distress alert.   

3. 

After the distress alert is transmitted (this takes about 40 seconds), the equipment 

waits for the distress acknowledgement call (DIST ACK) from a coast station. This 
usually takes less than three minutes. (If it is not received within 4.5 minutes, the 
distress alert is re-transmitted.)   

4. 

The radiotelephone automatically sets the distress communication frequency to use to 

conduct voice communications (telex also available) with the coast station.
