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.

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.
