INSTRUCTION MANUAL
COMMUNICATIONS RECEIVER
iR20
This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause
harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
WARNING: MODIFICATION OF THIS DEVICE TO RECEIVE CELLULAR RADIO TELEPHONE SERVICE SIGNALS IS PROHIBITED
UNDER FCC RULES AND FEDERAL LAW.
FOREWORD
IMPORTANT
Thank you for purchasing this Icom product. The IC-R20 COMMUNICATIONS RECEIVER is designed and built with Icom’s superior technology and craftsmanship. With proper care, this
product should provide you with years of trouble-free operation.
READ ALL INSTRUCTIONS carefully and completely
We want to take a couple of moments of your time to thank you
for making your IC-R20 your radio of choice, and hope you
agree with Icom’s philosophy of “technology first.” Many hours of
research and development went into the design of your IC-R20.
D FEATURES

PRECAUTION
RWARNING! NEVER operate the receiver with a earphone, headphones 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.
RWARNING! NEVER connect the receiver to an AC
NEVER expose the receiver to rain, snow or any liquids.
The receiver may be damaged.
NEVER operate or touch the receiver with wet hands. This
may result in an electric shock or damage the receiver.
NEVER solder the battery cell. This may damage the battery.

shock.
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).
ving a vehicle. Safe driving requires your full attention—anything less may result in an accident.
RWARNING! NEVER throw a battery cell or battery
pack into a fire since as internal battery gas can cause explosion.
RWARNING! NEVER disassemble the battery pack.
If the battery cell’s internal material (electrolyte liquid) gets
into your eyes, wash your eyes with water and obtain treatment from an eye doctor immediately.
AVOID the use of chemical agents such as benzine or alcohol when cleaning, as they can damage the receiver’s surfaces.
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, and will need to be recharged.
RESPECT other peaple’s privacy. Information overheard
but not intended for you cannot lawfully be used in any way.
NEVER connect the receiver to a power source of more
than 6 V DC directly. This will damage the receiver.
For U.S.A. only
NEVER connect the receiver to a power source using reverse polarity. This will damage the receiver.
CAUTION: Changes or modifications to this device, not expressly approved by Icom Inc., could void your authority to
operate this device under FCC regulations.

SUPPLIED ACCESSORIES
OPERATING THEORY
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 ICR20 receives RF energy from 0.150 MHz* to 3304.999 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 hertz, MHz is abbreviation
of megahertz or 1,000,000 hertz, where hertz is a unit of frequency.

iii
The IC-R20 may receive its own oscillated frequency, resulting in no reception or only noise reception, on some frequencies.
The IC-R20 may receive interference from extremely strong
signals on different frequencies or when using an external
high-gain antenna.

D Battery caution
D Regular charging
• CAUTION! NEVER short the battery terminals. Also, current
may flow into nearby metal objects such as a necklace, so
be careful when placing battery pack in handbags, etc.
q Attach the battery pack (BP-206) to the receiver. (See
page 8)
wPlug the AC adaptor (BC-149A/D*) into an AC outlet; or the
optional CP-18A/E into a cigarette lighter socket.
• NEVER incinerate used battery pack or battery cells. Internal battery gas may cause explosion.
• NEVER mix old and new batteries.
• Make sure all battery cells are the same brand, type and
capacity.
Either of the above may cause a fire hazard or damage the
receiver if ignored.
* Not supplied with some versions.
e Insert the adaptor plug into [DC] of the receiver.
• Charging periods: 8 hours (w/BP-206)
IC-R20
D Charging caution
• Recommended temperature for charging:
±0˚C to +35˚C (; +32˚F to +95˚F)
• Connect the supplied (or optional for some versions) AC
adaptor or optional cigarette lighter cable only when charging the battery pack (BP-206). NEVER use other manufacture’s chargers.
CAUTION: BE SURE to disconnect the CP-18A/E from
the cigarette lighter socket when charging is finished, because, a slight current still follows in the CP-18A/E and the
vehicle’s battery will become exhausted.

If the fuse blows or the receiver stops functioning while operating with the optional CP-18A/E, find the source of the problem if possible, and replace the damaged fuse with a new
rated one (FGB 5 A) as shown below.
The optional BC-156 provides rapid charging of battery
packs.
• Charging periods: 2.5 hours (w/BP-206)
Shorten or remove
the antenna.
Turn power OFF.
Check the
orientation.

CAUTION: Shorten or remove the telescoping antenna before charging to prevent the receiver from overturning.
If the charge indicator flashes orange, there may be a
problem with the battery pack (or charger). Reinsert the

■ Receive mode selection
■ Lock function
Receive modes are determined by the physical properties of
the radio signals. The receiver has 6 receive modes: FM,
WFM, AM, LSB, USB and CW modes. The mode selection is
stored independently in each band and memory channels.
To prevent accidental frequency changes and unnecessary
function access, use the lock function.
Typically, AM mode is used for the AM broadcast stations
(0.495–1.620 MHz) and VHF air band (118–135.995 MHz),
and WFM is used for FM broadcast stations (76–107.9 MHz).

■ Attenuator function
■ RF gain
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 receiver gain can be reduced with the RF gain setting.
This may help to remove undesired weak signals while monitoring strong signals. The RF gain may be useful for setting a
minimum level at which to hear signals for SSB/CW modes .
➥ Push [ΩΩ ATT] for 1 sec. to toggle the attenuator function
ON and OFF.

■ Tone scan
By monitoring a signal that is being operated with pocket

tone frequency or DTCS code necessary to open a squelch.
qSet the frequency to be checked for a tone frequency or
code.
wTurn the desired tone type, tone squelch or DTCS, ON by
holding [7 TONE] with turning [R-DIAL].
• One of “TSQL” or “DTCS” appears.
• Even the pocket beep function is activated, the function is cancelled when starts the tone scan.
ePush [4 T-SCAN] for 1 sec. to start the tone scan.
r When the CTCSS tone frequency or 3-digit DTCS code is
matched, the squelch opens and the tone frequency or
code 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.
☞ NOTE: The decoded tone frequency or code is programmed temporarily when a memory channel is selected. However, this will be cleared when the memory
channel is re-selected.
