POCKET BEEP AND TONE SQUELCH
q
Set the operating frequency.
w
Program the CTCSS tone frequency or DTCS code in set
mode.
• See p. 18 for programming details.
e
Push [TONE(T-SCAN)] several times. “T SQL” appears in
the function display.
r
When a signal with the matched tone is received, the
squelch opens and the signal can be heard.
• When the received signal includes an unmatched tone, the
squelch does not open. However, the S/RF indicator shows the
received signal strength.
• To open the squelch manually, push [MONI(ANM)].
t
Operate the transceiver in the normal way (push [PTT] to
transmit; release [PTT] to receive).
y
To cancel the tone squelch, push [TONE(T-SCAN)].
• “T SQL” disappears from the function display.
z
Set the operating frequency.
x
Program the CTCSS tone frequency or DTCS code in set
mode.
• See p. 18 for programming details.
c
Push [FUNC] then [
o
T SQL] to turn the tone squelch ON.
v
When a signal with the matched tone is received, the
squelch opens and the signal can be heard.
• When the received signal includes an incorrect tone,
the squelch does not open. However, the S/RF indi-
cator shows the received signal strength.
• To open the squelch manually, push [
q
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 [
G
T-OFF].
■
Tone scan
By monitoring a signal that is being operated with pocket
beep or tone squelch function, you can determine the tone
frequency necessary to open a squelch.
q
Set the channel to be checked for a tone frequency.
w
Push [
(TONE)
T-SCAN] for 1 sec. to start the tone scan.
• To change the scanning direction, rotate the tuning dial.
e
When the CTCSS tone frequency or 3-digit DTCS code is
matched, the squelch opens and the tone frequency is
temporarily programmed into the selected mode such as
memory or call channel.
• The tone scan pauses when a CTCSS tone frequency or 3-digit
DTCS code is detected.
• The decoded CTCSS tone frequency or 3-digit DTCS code is
used for the tone encoder or tone encoder/decoder depending
on the tone squelch ON/OFF setting.
r
Push [V/MHz(SCAN)] to stop the scan.
z
Set the channel to be checked for a tone frequency.
x
Push [F-2] for 1 sec. to start the tone scan.
c
When the tone frequency is matched, the squelch opens
and the tone frequency is programmed into the selected
mode such as memory or call channel.
v
Push [clr A(MW)] to stop the scan.
☞
NOTE:
The decoded tone frequency is programmed tem-
porarily when a memory or call channel is selected. How-
ever, this will be cleared when overwriting the memory/call
channel.
