Basic procedure

1.Prepare message and transmit it by pressing the [CALL] key. The DSC-60 then awaits acknowledgement of the call.

2.Receive acknowledge back (ACK BQ) signal from receiving station (coast station or ship station) within about five minutes. The audio alarm sounds at this time; press the [CANCEL] key to silence it.

3.After receiving ACK BQ signal, communicate with coast station; the FURUNO SSB radiotelephone sets the working frequency and class of emission specified by your ship.

1.3Audio Alarms

When you receive a distress alert or routine call addressed to your ship the audio and visual alarms are released. For the distress or urgent call, the audio alarm sounds until the [CANCEL] key is pressed. For other calls, the audio alarm sounds for one second and then automatically goes off.

The tone of the alarm depends on the call received. By becoming accustomed to the tone you can know which type of call you have received.
