■ Tone/DTCS squelch operation
The tone squelch or DTCS squelch opens when a sig-
nal with the same pre-programmed subaudible tone or
DTCS code is received.
The reverse tone or DTCS squelch is convenient when
you want to ignore the specifi c signal. The transceiver
closes the squelch when a signal with the same pre-
programmed subaudible tone or code is received.
q Set the operating frequency.
w Push [SET] to enter the Set mode.
e Set the tone frequency, or DTCS code and DTCS
polarity. (p. 45)
r Push any key other than [SET] or [MONI] to exit the
Set mode.
t Push [TONE] several times to select the desired
tone or code.
- “ ” : Tone squelch
- “ ” : DTCS squelch
- “ ” : Reverse tone squelch
- “ ” : Reverse DTCS squelch
y Operate the transceiver in the normal way; push
[PTT] to transmit; release [PTT] to receive.
• To manually open the squelch, push [MONI].
When the tone or DTCS is in use:
When a matched tone is received, the squelch opens
and audio is heard.
• If the signal includes an unmatched tone, the
squelch does not open. However, the S/RF meter
shows the signal strength.
When the reverse tone or DTCS is in use:
When a matched tone is received, the squelch re-
mains closing.
• If the signal includes a matched tone, the squelch
does not open. However, the S/RF meter shows the
signal strength.
u To cancel the tone or DTCS squelch, push [TONE]
several times, until the tone icon disappears.
Using the HM-133V
z Set the operating frequency.
x Program the CTCSS tone frequency or DTCS code
in the Set mode. (p. 45)
c Push [FUNC] then [TSQL] or [DTCS] , to
turn ON the tone squelch or DTCS squelch.
v When a matched tone is received, the squelch opens
and audio is heard.
• If the signal includes an unmatched tone, the
squelch does not open. However, the S/RF meter
shows the signal strength.
• To manually open the squelch, push [MONI] .
b Operate the transceiver in the normal way ;push
[PTT] to transmit; release [PTT] to receive.
n To cancel the tone squelch, push [FUNC] then
[T-OFF] .
