11 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 [oT 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 [qMONI].
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 [GT-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.
