DIGITAL MODE OPERATION
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 slow
data communication.
q
Set the operating frequency.
w
Program the digital code or call sign in setting mode.
• See p. 69, “Digital code setting” or pgs. 59, 60 “Call sign programming.”
e
Push
[TONE
]
several times until “ ” or “ ” ap-
pears in the function display.
• “
” for digital code squelch; “
” for call sign squelch operation.
r
When a signal with the matched digital code/call sign is re-
ceived, the squelch opens and the signal can be heard.
• When the received signal includes an unmatched digital
code/call sign, the squelch does not open. However, the S/RF
indicator shows the received signal strength.
• To open the squelch manually, rotate
[SQL]
counter clockwise.
t
Operate the transceiver in the normal way (push
[PTT]
to
transmit; release
[PTT]
to receive).
y
To cancel the digital code/call sign squelch, push
[TONE
]
several times until “ ” or “ ” disappears.
NOTE:
While in the digital mode operation, the monitor
function (pushing
[MONI
]
) works as the analog mon-
itor for receiving an FM signal. The digital monitor function
is activate using the Squelch control knob [SQL].
z
Set the operating frequency.
x
Program the digital code or call sign in setting mode.
• See p. 69, “Digital code setting” or pgs. 59, 60 “Call
sign programming.”
c
Push
[FUNC]
then
[

or
[

to turn the digital code or call sign squelch ON.
v
When a signal with the matched digital code or
call sign is received, the squelch opens and the
signal can be heard.
• When the received signal includes an unmatched digital
code or call sign, the squelch does not open. However,
the S/RF indicator shows the received signal strength.
• To open the squelch manually, push

several times until less than squelch level 7.
b
Operate the transceiver in the normal way (push

to receive.
n
To cancel the digital code or call sign squelch,
push

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.
