CONTINUOUS TONE CODED
SQUELCH SYSTEM FEATURES
Your transceiver can transmit and receive a low-level, selectable
subaudible tone at the same time as it transmits (TX) or receives
(RX) a regular signal. This special tone lets you listen only to oth-
er transceivers set to the same tone frequency when you use the
transceiver in simplex operation. It also lets you match your trans-
ceiver to the subaudible tone frequency used by a local repeater.
To enable the TX and RX tones for the transceiver, follow these
steps.
1. Press
F
+
T-SQ
. The current tone setting and
T
appear. (
T
indicates that only the TX tone is enabled.)
2. Rotate the tuning control or repeatedly press
UP
or
DN
to
select a tone frequency from the list on Page 28. About 5
seconds after your last change, the display exits the tone
setting mode, stores your tone selection, and the current
operating frequency appears again.
3. To enable both the TX and RX tones, repeatedly press
F
+
T-
SQ
until
T-SQ
appears. To disable CTCSS operation,
repeatedly press
F
+
T-SQ
until
T
and
T-SQ
disappear.
4. Press
PTT
to store all the settings.
TEMPORARILY OPENING SQUELCH
If you use the Tone Squelch (CTCSS) feature, you might not hear
a transmission on the current frequency. To temporarily open the
squelch so you can hear all transmissions on the frequency, hold
down
F
. To resume normal operation, release
F
.
