■ 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 [1•
TONE
]
one or more times until or “ ” or “ ” disappears.
■ Digital monitor
This function is used to listen to the analog signal (FM mode
signal) without changing the operating mode during digital
(DV mode) operation.
q While pushing and holding [
YY
] and [
ZZ
], turn the power ON
to enter
INITIAL SET MODE
.
w Push [
YY
] or [
ZZ
] several times until “dmO” appears.
e Rotate [VOL] to turn the digital monitor setting to “An” or
“dG.”
• “An”:Activate for monitoring the analog (FM mode) signals.
(default)
• “dG”:Activate to open the call sign or digital code squelch.
r Push [✱•
ENT
] (or [D•
CLR
]) to exit
INITIAL SET MODE
.
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 [MONI] and [
YY
] or [
ZZ
]).
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.
