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
separate memory channels (pgs.
35, 36)
What is VFO?
VFO is an abbreviation of Variable Frequency Oscillator. Fre-
quencies for receiving are generated and controlled by theVFO.
Operating
band selection
The receiver can receive the
broadcast band, HF band, 50
MHz band, FM broadcast
band, VHF avionics band, 144
MHz band, 300 MHz band,
400 MHz band, 800 MHz
band,* 1200 MHz, 2400 MHz
or TV band.
* Some frequencies cannot be re-
ceived with the U.S.A. version.
➥Push [↔] several times to
select the desired band.
•When a memory channel is
selected, the first push of [↔]
selects VFO mode.
Amateur TV screen is also
selected for the ATV-type
IC-R3. (p. 36)

3FREQUENCY AND CHANNEL SETTING
Setting a frequency
qSelect the desired band with [↔].
wRotate [DIAL] to change the frequency.
•The frequency changes according to the preset tuning steps.
See the right section for selecting the tuning step.
•Some TV channels may be set as skip channels by default and
can be selected by rotating [DIAL] while pushing [FUNC]. (p. 34).
•Push [↔] while pushing [FUNC] to change the frequency in 100
kHz, 1 MHz or 10 MHz steps.
The 1 MHz tuning step (dial select step) can be set to 100
kHz, 1 MHz or 10 MHz tuning steps in set mode. See p.
39 for details.
Setting a tuning step
Tuning steps can be selected for each band, however, the
tuning step of the broadcast band is fixed to 9 kHz steps ex-
cept for U.S.A. and Canada versions. The following are avail-
able.
•5 kHz•6.25 kHz*•10 kHz•12.5 kHz•15 kHz
•20 kHz•25 kHz•30 kHz•50 kHz•100 kHz
* Not available for 1200 MHz band.
qSelect the desired band, except for TV band, with [↔].

ory channel is selected.
wRotate [DIAL] to change the indi-
cated memory channel.

Lock function
The lock function prevents accidental frequency changes and
accidental function access.
➥Push [FUNC] + [MODE] for 2 sec. to toggle the lock func-
tion ON and OFF.

of 4 groups in set mode. See p. 42
for details.
Attenuator 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 sta-
tion, are near your location.
The receiver has 4 attenuation levels for various operating
conditions. The attenuator functions when the operating fre-
quency is 1149.995 MHz or below.
qPush [FUNC] + [(SQL) ATT] to enter the attenuator setting
condition.
wRotate [DIAL] to set the attenuation level 1–4 or turn the
attenuator function OFF.
•“ATT1” – “ATT4” appears in the color LCD when the color LCD is
ON; “AT T” appears in the sub display when the color LCD is
OFF.

Receiving
Make sure a charged battery pack or alkaline batteries are in-
stalled. (pgs. 1, 46)
qPush [POWER] for 2 sec. to turn power ON.
wPush [↕] to set the desired audio level.
•One of the LCDs shows the volume level while setting. See the
next page for details.
ePush [↔] to select an operating band. (p. 7)
rRotate [DIAL] to set an operating frequency. (p. 8)
tSet the squelch level.
•While pushing [SQL], rotate [DIAL].
•The first click of [DIAL] indicates the current squelch level.
•“LEVEL1” is loose squelch and “LEVEL9” is tight squelch.
•“AUTO” indicates automatic level adjustment with a noise pulse
count system.
•Push and hold [SQL] to open the squelch manually. (default be-
haviour; p. 41)
yWhen a signal is received:
➥Squelch opens and audio is emitted from the speaker.
➥The S indicators show the relative signal strength.
➥The busy indicator appears when receiving a signal or when the
squelch is open.
q Power switch w Set volume
e Select band

For non-U.S.A. versions
If the display mode selection is set as ‘manual’(p. 43) with
the color LCD ON, the receiver may not be able to turn it-
self OFF when the battery becomes exhausted.
Replace the battery and turn power OFF in this case.
For U.S.A. version
The U.S.A. version automatically turns itself OFF when the
receiver detects that battery replacement is necessary. Re-
place the battery or charge the battery pack in this case.

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.
•One of the LCDs shows the volume level while setting.
Setting squelch level
The squelch circuit mutes the received audio signal depend-
ing on the signal strength. The receiver has 9 squelch levels,
a continuously open setting and an automatic squelch setting.
➥While pushing [SQL], rotate the
[DIAL] to select the squelch level.
•The first click of [DIAL] indicates the
current squelch level.
•“LEVEL1” is loose squelch and

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 3 receive modes: FM, AM
and WFM modes. TV and ATV (ATV type only) also use WFM
mode. The mode selection is stored independently in each
band and memory channels.
Typically, AM mode is used for the AM broadcast stations
(0.495–1.620 MHz) and air band (118–135.995 MHz), and
WFM is used for FM broadcast stations (76–107.9 MHz).
➥Push [MODE] one or more times to select the desired re-
ceive mode.
