FOREWORD

READ ALL INSTRUCTIONS carefully and completely

before using the receiver.

SA VE THIS INSTRUCTION MANUAL — This in-

struction manual contains important operating instructions for
the IC-R2.

EXPLICIT DEFINITIONS

The explicit definitions below apply to this instruction manual.

CAUTIONS

RWARNING! NEVER operate the receiver with a head-

set or other audio accessories at high volume levels .Hearing
experts advise against continuous high volume operation. If
you experience a ringing in your ears, reduce the volume level
or discontinue use.

AVOID using or placing the receiver in direct sunlight or in

areas with temperatures below –10°C (+14°F) or above
+60°C (+140°F).

Even when the receiver power is OFF, a slight current still
flows in the circuits.Remove batteries from the receiver when
not using it for a long time. Otherwise, the installed batteries
will become exhausted.

For U.S.A. only

CAUTION:Changes or modifications to this device, not ex-

pressly approved by Icom Inc., could void your authority to
operate this device under FCC regulations.

WORD

WARNING

CAUTION

NOTE

DEFINITION

Personal injury, fire hazard or electric
shock may occur.

If disregarded, inconvenience only. No risk
of personal injury, fire or electric shock.

Equipment damage may occur.

Versions of the IC-R2 which display “CE” on the serial number
seal, comply with the essential requirements of the 89/336/EEC
directive for Electromagnetic Compatibility.

*Not supplied with some versions.

OPERATING THEOR Y

Electromagnetic radiation which has frequencies of 20,000
Hz (20 kHz*) and above is called radio frequency (RF) energy
because it is useful in radio transmissions.The IC-R2 re­ceives RF energy from 0.495 MHz* to 1309.995 MHz and
converts it into audio frequency (AF) energy which in turn ac­tuates a loudspeaker to create sound waves. AF energy is in
the range of 20 to 20,000 Hz.

* kHz is an abbreviation of kilohertz or 1000 her tz, MHz is abbrevia-

tion of megahertz or 1,000,000 her tz, where hertz is a unit of fre ­quency.

OPERATING NOTES

The IC-R2 may receive its own oscillated frequency, resulting
in no reception or only noise reception, on some frequencies.

The IC-R2 may receive interference from extremely strong
signals on different frequencies or when using an external
high-gain antenna.

ACCESSORY ATTACHMENT

D Antenna

Insert the supplied antenna into the an­tenna connector and screw down the an­tenna as shown at right.

Keep the jack cover attached when jack
is not in use to avoid bad contacts from
dust and moisture.

Commercially available antennas may increase receiver per­formance. An optional AD-92SMA

ANTENNA CONNECTOR

ADAPTER is available to connect an antenna with a BNC con-

nector.

D Battery installation

q Remove the battery cov er

from the receiver .

w Install 2 R6 (AA) size al-

kaline, dry cell or Ni-Cd
batteries.

•Be sure to observe the cor­rect polarity.

•Charge Ni-Cd batteries be­fore use. (See the separate
BC-127A/D instruction
sheet.)

Keep battery contacts clean. It’s a good idea to clean bat-
tery terminals once a week.

DBelt clip

Conveniently attaches to
your belt.

Slide the belt clip into the
plastic loop on the back of
the receiver.

FREQUENCY AND CHANNEL SETTING

■ VFO and memory channels

This receiver has 2 normal operating modes:VFO mode and
memory mode.

VFO mode is used for setting a desired frequency within the
frequency coverage.
➥Push [V/M] to select VFO mode.

Memory mode is used for operation of memory channels
which have programmed frequencies.
➥Push [V/M] to select memory

mode.

•To program a memory, refer to p.12.

What is VFO?

VFO is an abbreviation of Variable Frequency Oscillator. Fre­quencies for receiving are generated and controlled by the
VFO.

■ Operating band selection

The receiver can receive
the broadcast band, HF
band, 50 MHz band, VHF
avionics band, 144 MHz
band, 300 MHz band, 400
MHz band, 800 MHz band*
or 1200 MHz band.
➥Push [BAND] several

times to select the de­sired band.

•When a memory channel
is selected, the first push
of [BAND] selects VFO
mode (and transfers the
memory channel con­tents).

➥Rotate [DIAL] while

pushing [BAND] to select
the desired band.

*Some frequencies can-

not be received with
the U.S.A.version.

MHz steps (default;p. 26).

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.26
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 except
for U.S.A. and Canada versions.The following are available.

•5 kHz •6.25 kHz •10 kHz •12.5 kHz •15 kHz

•20 kHz •25 kHz •30 kHz •50 kHz •100 kHz

DUsing the [TS] switch

q Select VFO mode with [V/M].
w Select the desired band with

[BAND].

e Push [TS] to enter tuning step set-

ting condition.

r Rotate [DIAL] to select the desired tuning step.
t Push [TS] to return to normal operation.

DUsing set mode

q Select VFO mode with [V/M].
w Select the desired band with [BAND].
e Push [V/M] for 2 sec.to enter set mode.
r Rotate [DIAL] until “STEP”appears.

•“STEP” disappears after 1 sec. and the previously selected tun-
ing step and “tS”appear.

ON and OFF.

•[POWER], [VOL] and [SQL] can still
be accessed while the lock function
is ON (default).

of 4 groups in expanded set mode.
See p.28 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 sta­tion, are near your location.

The attenuator has approx.10 dB attenuation.
