D Turning ON the Tone Squelch
Before turning ON the Tone Squelch, set the desired
CTCSS tone frequency or DTCS code in the Set
mode.
➥ Hold down [MONI] for 2 seconds to turn ON the
Tone Squelch.
• Holding down [MONI] for 2 seconds switches
between “TSQL” (Tone Squelch), “TSQL
ë ”
(Pocket Beep) and OFF (cancel).
Tone Squelch
The transceiver is equipped with 51 CTCSS
(subaudible) tone frequencies, and 104 DTCS codes.
CTCSS/DTCS operation enables you to communicate
in the silent standby mode, since you will only receive
calls from group members using the same CTCSS
tone frequency or DTCS code.
Information
The transceiver has 51 tone frequencies and
consequently their spacing is narrow compared to
units having 38 tones.
Therefore, some tone frequencies may receive
interference from adjacent tone frequencies.
D Setting the
CTCSS tone frequency/DTCS code
1) Enter the Set mode.
➥ Hold down [FUNC] for 2 seconds.
2) Select the CTCSS/DTCS menu.
➥ Push [FUNC].
• Selected CTCSS or DTCS code is displayed.
• Push [MONI] to select between CTCSS and DTCS
to enter the Setting mode.
3) Set the desired CTCSS tone frequency or DTCS
code.
➥ Push [UP]/[DOWN].
4) Exit the Set mode.
➥ Hold down [FUNC] for 2 seconds.
