BASIC OPERATION
■ Lock functions
■ Attenuator function
To prevent accidental frequency changes and unnecessary
function access, use the lock function.
The attenuator prevents a desired signal from distorting when
very strong signals are near the desired frequency or when
very strong electric fields, such as from a broadcasting station, are near your location. The attenuator gain is about 20
dB and this function can be activated on 1300 MHz or below.
➥ Continue to hold [SET•
] down for 2 sec. after power
ON to turn the lock function ON and OFF.

BASIC OPERATION
■ Duplex operation
Duplex communication uses two different frequencies for
transmitting and receiving. Generally, duplex is used in communication through a repeater, some utility communications,
etc.
rPush [SET•SKIP] once to select the offset frequency setting item.
tRotate [DIAL] to set the desired offset frequency within
0.000–1000.000 MHz range.
During duplex operation, the transmit station frequency is

POCKET BEEP AND TONE SQUELCH
■ Tone/DTCS squelch operation
The tone or DTCS squelch opens only when receiving a signal with the same pre-programmed subaudible tone or DTCS
code, respectively. You can silently wait for the specified signal using the same tone.
q Set the operating frequency in FM mode.
w Program the CTCSS tone frequency or DTCS code in set
mode. ((p. 31))
e Push and hold [MONI•T/T-SCAN] for 1 sec. to enter
tone squelch selection mode, then rotate [DIAL] until “ ”
or “ ” appears in the function display.
r When a signal with the matched tone is received, the
squelch opens and the receiver emits audio.
• When the received signal includes an unmatched tone, the
squelch does not open. However, the S-meter indicator shows
the received signal strength.
• To open the squelch manually, push [MONI•T/T-SCAN].
t To cancel the tone squelch or DTCS squelch function, repeat steps e until “oFF” appears, then push any switch.
D Reverse action for tone or DTCS squelch
➥ Enter tone squelch selection mode as described in steps
q to e as shown left, then rotate [DIAL] to select either
reverse action for the tone or DTCS squelch as below.

How does the Reverse action work?
When the reverse action is selected for either the tone
squelch, “tSqL-r,” or DTCS squelch, “dtCS-r,” and a signal
with the matched tone (or DTCS) is received, the squelch
closes, and the receiver mutes the signal. You can listen in
the signals any other than the specified one, if it’s with tone.

■ Tone scan
By monitoring a signal that is being operated with pocket
beep, tone or DTCS squelch function, you can determine the
tone frequency or DTCS code necessary to open a squelch.
q Set the desired operating frequency or memory channel to
be checked for a tone frequency or code.
w Push and hold [MONI•T/T-SCAN] for 1 sec and rotate
[DIAL] to select the tone type, tone squelch or DTCS, to
be scanned.
• Either “ ” or “
” appears.
e Push and hold [MONI•T/T-SCAN] for 1 sec. to start the
tone scan.
• To change the scanning direction, rotate [DIAL].
[MONI•T/T-SCAN]
During CTCSS frequency scan
r 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 condition such
as memory 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 decoder depending on the selected tone condition or type in step w.

OTHER FUNCTIONS
■ Partial reset
AT
POWER ON
If you want to initialize the operating conditions (VFO frequency, VFO settings, set mode contents) without clearing
the memory contents, a partial resetting function is available
for the receiver left and right bands independently.
➥ While pushing desired band’s [VFO/MR•S.MW], turn the
power ON to partially reset the desired band (left or right).
■ ALL reset
AT
POWER ON
The function display may occasionally display erroneous information (e.g. when first applying power). This may be
caused externally by static electricity or by other factors.
If this problem occurs, turn power OFF. After waiting a few
seconds, turn power ON again. If the problem persists, perform the following procedure.
• Partial resetting is also available. See left for details.
IMPORTANT!:
Resetting the receiver CLEARS all memory information
and initializes all values in the receiver.
Left band partial reset.
Right band partial reset.
✔ Hint!
When pushing both [VFO/MR•S.MW] and turning the power
ON, partially reset both bands at the same time.
➥ While pushing both band’s [MHz•TS], turn the power ON
to reset the CPU.
