■
Digital squelch functions
The digital code (CSQL) or call sign (DSQL) squelch opens
only when receiving a voice signal with the same pre-pro-
grammed digital code or call sign, respectively. The digital
code or call sign squelch does not function while in a low-
speed data communication.
q
Set the operating frequency.
w
Program the digital code or call sign.
• See p. 53, “Digital code setting” or p. 42 “Call sign program-
ming.”
e
Push
[1•
TONE
]
one or more times until “ ” or “ ” appears
in the function display.
• “ ” for call sign squelch; “ ” for digital code squelch operation.
r
When a signal with the matched call sign/digital code is re-
ceived, the squelch opens and the signal can be heard.
• When the received signal includes an unmatched call sign/digital
code, the squelch does not open. However, the S-meter shows
the received signal strength.
• To open the squelch manually, push and hold
[MONI]
.
t
Operate the transceiver in the normal way (push
[PTT]
to
transmit; release
[PTT]
to receive).
y
To cancel the call sign/digital code squelch, push

Digital monitor
This function is used to listen to the analog signal (FM mode
signal) without changing the operating mode during digital

NOTE:
When “digital monitor setting” is set to “An (ana-
log),” the monitor function (pushing
[MONI]
) works as the
analog monitor for receiving an FM signal. Then digital
monitor function is activated using the Squelch control
(pushing

USING
INITIAL SET MODE
✔
While scanning in digital mode:
• The call sign squelch function deactivate, then after can-
celling the scan it will activate again.
• Scan stops near channel in a 5 kHz tuning steps, and then
no sound comes out.
