3FREQUENCY AND CHANNEL SETTING
VFO and memory channels
This receiver has 2 normal operating modes: VFO mode and
memory mode.
VFO modeis used for setting a de-
sired frequency within the fre-
quency coverage.
➥Push [V/M] to select VFO mode.
Memory modeis used for opera-
tion of memory channels which
have programmed frequencies.
➥Push [V/M] to select memory
mode.
•“X” or “M:” appears when a mem-
ory channel is selected.
•To program a memory, refer to p.
14.
•TV band and ATV (ATV type) have

Selecting a memory channel
qPush [V/M] to select memory
mode.
•“X” or “M:” appears when a mem-
ory channel is selected.
wRotate [DIAL] to change the indi-
cated memory channel.
•Only programmed memory chan-
nels can be selected.
•Rotate [DIAL] while pushing [FUNC]
to change the memory bank.
Lock function
The lock function prevents accidental frequency changes and
accidental function access.

4BASIC OPERATION
Setting volume level
The audio level can be adjusted through 32 levels.
➥Push [↕] to set the desired audio level.
•Beep tone sounds while setting. This indicates the approximate
sound level. (default behaviour; p. 40)
•Pushing and holding these keys changes the audio level contin-
uously.

4BASIC OPERATION
Monitor function
This function is used to listen to weak signals or to open the
tone squelch manually.
➥Push and hold [SQL] to monitor the operating frequency.
•“RX” flashes while monitoring.
The [SQL] switch can be set to ‘sticky’operation in set
mode. (p. 41)
You can monitor duplex communication by pushing the
[SQL] switch when the duplex function is in use. (p. 31)
Receive mode selection
Receive modes are determined by the physical properties of
the radio signals. The receiver has...

4BASIC OPERATION
TV screens cannot be selected by pushing [MODE]. See p.
34 for TV operation details.
Display backlighting
The receiver has display backlighting with a 5 sec. timer for
nighttime operation. The display backlighting can be turned
ON continuously or turned OFF, if desired.
➥Push any switch except [FUNC]; or, rotate [DIAL] to turn
the backlighting ON.
•When auto backlighting is set, the backlighting will automatically
turn OFF when switches and [DIAL] have not been operated for
5 sec....

General
The receiver has 400 memory channels in 8 banks (A–H) for
storage of often-used frequencies.
◊Memory channel contents
The following information can be programmed into memory
channels:
•Operating frequency (p. 8)
•Receive mode (p. 12)
•Tuning step (p. 8)
•Memory name (p. 17)
•Duplex direction (DUP or –DUP) with an offset frequency
(p. 31)
•Tone squelch ON/OFF (p. 28)
•Tone squelch frequency (p. 28)
•Scan skip setting (p. 22)

Programming after selection
qSelect memory mode with [V/M].
wSet the memory channel to be programmed with [DIAL].
•Rotate [DIAL] while pushing [FUNC] to select a memory bank
(A–H) or programmed scan edge channel.
•Non-programmed channels cannot be selected.
ePush [V/M] to select VFO mode.
rSet the desired frequency:
➥Select the desired band with [↔].
➥Set the frequency using [DIAL].
