11.5.4 Transmitting an Individual Call
This feature allows the user to contact another vessel with a DSC radio. This
feature is similar to calling a vessel on CH16 and requesting to go to another
channel.
Pre-Programmable Calling
1. Press the [CALL(MENU)] key. The “DSC Operation”
menu will appear.
2. Turn the CHANNEL selector knob to select “Indi-
vidual.” (To cancel, select “Exit” with the CHANNEL
selector knob or press the [16/9] key.)
3. Press the [ENT] key. The transceiver will beep, and
the “Individual directory” will appear.
4. Turn the CHANNEL selector knob to select the “Indi-
vidual” you want to contact.
5. Press the [ENT] key, then turn the CHANNEL selec-
tor knob to select the operating channel you want to
communicate on and press the [ENT] key.
6. Press the [ENT] key again to transmit the individual
DSC signal.
7. After INDIVIDUAL CALL is transmitted, the trans-
ceiver will wait 8 seconds for the acknowledgment. If
the reply signal is not received, the transceiver will
transmit again.
8. After the second INDIVIDUAL CALL is transmitted, if the reply signal is not
received, the display will be as shown in the illustra-
tion on the right. To send the call again, press the
[ENT] key.
9. When an individual call acknowledgment is received,
the established channel is automatically changed to
the channel which is selected on step 5 above and a
ringing tone sounds.
10. Press any key to listen to the channel to make sure it
is not busy, then key the microphone and call the
other vessel you desire to communicate with.
