TONE SQUELCH AND POCKET BEEP
Tone Squelch
• ”List number” is the number in the grey column in the
table to the right.
r
Rotate [ROTARY SELECTOR] to set the desired
CTCSS tone frequency or DTCS code.
t
Hold down [TOP] for 2 seconds to save and exit the
Set mode.
The transceiver is equipped with 51 CTCSS 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.
NOTE
: Channels 5 and 35 are used for the
emergency channels, and the CTCSS/DTCS
function is not selectable on those channels.
Information
• Selectable CTCSS tone frequencies and DTCS codes are
listed to the right.
• 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
q
Hold down [TOP] for 2 seconds to enter the Set
mode.
w
Push [Side 1] or [Side 2] to select the CTCSS/DTCS
menu.
e
Push
to select between CTCSS and DTCS to
enter the setting mode.

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
as described to the left.
q
Rotate [ROTARY SELECTOR] to select the desired
channel (excluding channel 5 or 35).
w
Hold down [Side 1] for 2 seconds several times until
“TSQL” is displayed.
• Holding down [Side 1] for 2 seconds switches between
“TSQL” (Tone Squelch), “TSQL
ë
” (Pocket Beep) and
OFF (cancel).
• When you receive a signal with a matching tone or code,
the squelch opens, and you can hear the signal. When
you receive a signal that does not match, the squelch
does not open.
