DSC Operation

•

Sending DSC calls is done from menus similar to the Settings menu. Whereas entering the Settings menu required a press and hold of the Call/Set button, the sending menus appear with a press of the Distress button.

All received DSC calls will sound one (1) or another of the alarms to alert you to them. See pages 34 through 35 for descriptions of the different alarms. Pressing any button will turn Off the alarm while maintaining the received call information on the LCD.

Sending Distress Calls

The ability to send and receive distress calls and their acknowledgements on Channel 70 can literally be a lifesaver for you or another mariner.

NOTE

The DSC call will:

■Sound the distress alarm at all receiving stations.

■Inform receiving stations of your identity (MMSI).

■Inform receiving stations of your position if you have a GPS device connected or you have manually entered your position.

It will not provide the receiving stations with other distress information such as the nature of your problem, number of persons aboard, injuries, or the like. For that, you will have to communicate by voice on Channel 16 with the station that acknowledges your DSC distress call.

Distress Acknowledgement

The distress alarm will sound to let you know that the message is being sent. At the end of the transmission, the radio will maintain a watch on Channels 16 and Channel 70 for an acknowledgement. Press any button to turn Off the alarm and return to Standby mode.

If an acknowledgement is received, the distress alarm will sound again and the responding party’s MMSI number will show on the LCD.

If no acknowledgement is received, the radio will resend the message at approximately four (4) minute intervals until an acknowledgement is received or you abort the distress call.
