6.3 SENDING AN INDIVIDUAL CALL
This feature allows the user to contact another user vessel DSC and to
automatically switch the receiving DSC radio to a desired working channel.
This feature is similar to calling a vessel on CH16 and requesting to go to
another channel. To send an individual call, see section 7.5 INDIVIDUAL
DIRECTORY SETUP. The individual call function allows you to transmit a
DSC signal to a specific party only, prompting communication on a voice
channel.
1. Select the traffic channel for voice communica-
tion.
2. Press the [ CALL/SET
] key. The “DSC OPERA-
TION” menu will appear.
3. Turn the CHANNEL selector knob to select “INDI-
VIDUAL.” (To cancel, select “EXIT” with the CHAN-
NEL selector knob or press the [ 16/9
] key.)
4. Press the [ CALL/SET
] key. The transceiver will
beep, and the “Individual directory” will appear.
5. Turn the CHANNEL selector knob to select the
“Individual” you want to contact.
6. Press the [ CALL/SET
] key to transmit the indi-
vidual 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 transmit-
ted, if the reply signal is not received, the dot ma-
trix area of the LCD will display “
à
SEND” to prompt
the user to send the call again or exit the mode.
9. When an individual call acknowledgment “able to
comply” is received, the established channel is
automatically selected and an alarm sounds.
10. When an individual call acknowledgment with “un-
able to comply” is received, the established channel is automatically
selected.
11. To cancel, select “EXIT” using the CHANNEL selector knob and press
the [ CALL/SET
] key. This procedure can be also canceled by pressing
the [ CALL/SET
] key or [
16/9
] key.
