tric shock.
RWARNING! NEVER operate the receiver while dri-
ving a vehicle. Safety driving requires your full attention—any-
thing 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 an ex-
plosion.
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 treat-
ment from an eye doctor immediately.
NEVER connect the receiver directly to a power source of
more than 6 V DC. This will damage the receiver.
NEVER connect the receiver to a power source using re-
verse polarity. This will damage the receiver.
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 bat-
tery.

areas with temperatures below –10°C (+14˚ F) or above
+60°C (+140˚F).
AVOID the use of chemical agents such as benzine or al-
cohol in cleaning, as they can damage the receiver’s sur-
faces.
Even when the receiver power is OFF, a slight current still
flows in the circuits. Remove the battery pack or batteries
from the receiver while not using it for a long time. Otherwise,
the installed battery pack or batteries will become exhausted,
and will need to be recharged.

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

■ Programmed scan operation
25 pairs, 50 channels of memories are used for programmed
scan operation, that specify a scanning range. The pro-
grammed scan scans between “xxA” and “xxB” (xx=00 to 24)
frequencies. Therefore, before operating the programmed
scan, different frequencies must be programmed into “A” and
“B” channels.
DD
Programming scan edges
Astart frequency must be programmed into a “xxA,” and end
frequency must be programmed into a “xxB” memory channel.

■ Battery installation
Make sure receiver power is turned OFF before installing or
replacing the batteries.
qRemove the battery cover from the receiver.
wFor alkaline battery use, attach the supplied battery spacer.
eInstall 3 R6 (AA) size alkaline batteries.
• Be sure to observe the correct polarity.
Keep the battery contacts clean to avoid rust or poor contact.
It’s a good idea to clean the battery terminals once a week.
DD
Battery pack installation
q Remove the battery cover from the receiver.
w Remove the supplied battery spacer for R6 (AA) size bat-
tery use.

■ Caution
DD
Battery caution
CAUTION! NEVER short the battery terminals. Current will
flow into metal objects, so be careful when placing battery
pack in handbags, etc.
NEVER incinerate used battery packs 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.
DD
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.
AVOID leaving the battery pack in a fully charged, or com-
pletely discharged condition for long time. It causes shorter
battery life. In case of leaving the battery pack unused for a
long time, it must be kept safely after discharge, or use the
battery for 2 or 3 hours, then remove it from the receiver.
If your battery pack seems to have no capacity even after
being charged, fully charge the battery pack again. If the bat-
tery pack still does not retain a charge (or very little), a new
battery pack must be purchased.
CAUTION: BE SURE to disconnect the CP-18A/E from
the cigarette lighter socket when charging is finished, be-
cause, a slight current still follows in the CP-18A/E and the
vehicle’s battery will become exhausted.
■ Battery charging
DD
Regular charging
q Insert the battery pack (BP-206) into the receiver. (p. 8)
wPlug the AC adaptor (BC-149A/D*) into an AC outlet; or the
optional CP-18A/E into a cigarette lighter socket.
* Not supplied with some versions.
eTurn OFF the receiver, then insert the adaptor plug into
[DC] of the receiver.
RR
WARNING!: NEVER attempt to charge any other bat-
teries. Because the IC-R20 can charge the BP-206 only.

CP-18A/E fuse replacement
If the fuse blows or the receiver stops functioning while oper-
ating with the optional CP-18A/E, find the source of the prob-
lem if possible, and replace the damaged fuse with a new
rated one (FGB 5 A) as shown below.
DD
Rapid charging with the BC-156
The optional BC-156 provides rapid charging of battery pack
(BP-206).
• Charging periods: 2.5 hours (w/BP-206)
CAUTION: Shorten or remove the telescoping antenna be-
fore 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
battery pack or contact your dealer.
Turn power OFF.

Recommendation:
Charge the supplied battery pack for a maximum of
8 hours. Li-Ion batteries are different from Ni-Cd bat-
teries in that it is not necessary to completely charge
and discharge them to prolong the battery life. There-
fore, charging the battery in intervals, and not for ex-
tended periods is recommended.

Duplex communication uses 2 different frequencies for trans-
mitting and receiving. Generally, duplex is used in communi-
cation through a repeater, some utility communications, etc.
During duplex operation, the transmit station frequency is
shifted from the receive station frequency by the offset fre-
quency. Repeater information (offset frequency and shift di-
rection) can be programmed into memory channels. (p. 26)

■ 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.
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 when 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.
•To change the scanning direction, rotate [R-DIAL].
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 condi-
tion, such as memory channel.
• The tone scan pauses when a CTCSS tone frequency or 3-digit
DTCS code is detected.
✔
For your convenient!
Even if no tone type is selected, either tone squelch or DTCS,
pushing [4 T-SCAN] for 1 sec. will also start tone scan. In this
case, the tone scan searching for tone squelch frequency
only.
☞ NOTE: The decoded tone frequency or code is pro-
grammed temporarily when a memory channel is se-
lected. However, this will be cleared when the memory
channel is re-selected.

NOTES:
• Some noise or spurious may be received when the inter-
nal bar or earphone cable is used for antenna.
• The supplied or third party’s antenna MUST BE con-
nected to the antenna connector to receive signals other
than AM or FM broadcast bands.
• When receiving an AM broadcast signal with internal bar
antenna, aim the receiver to better audio direction.
• When the internal bar or earphone cable is used for an
antenna, the attenuator function cannot be used.

[REC].
eRotate [R-DIAL] to select the setting, then push [ REC].
rPush [DUALWATCH] to exit the recording set mode.
tPush [ REC] to activate.
NOTE: Before using this function, verify the squelch set-
ting as close level when no signal is received. Otherwise
this function will not pause even when signal disappears.
• Erasing recorded audio
NOTE: The IC recorder can erase all the tracks at the
same time, but cannot erase each track independently.
Only using the optional CS-R20
CLONING SOFTWARE
can
store the recorded audio into a PC or erase independently.
qPush [ REC] for 1 sec. to enter the recording set mode.
wRotate [R-DIAL] to select “ALL DELETE,” then push
[ REC].

■ Partial reset
If you want to initialize the operating conditions (VFO fre-
quency, VFO settings, set mode contents) without clearing
the memory contents, a partial resetting function is available
for the receiver.
➥ While pushing [VFO MHz], turn the power ON to partially
reset the receiver.
■ All reset
The function display may occasionally display erroneous in-
formation (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 for a few
seconds, turn power ON again. If the problem persists, per-
form the following procedure.
• Partial resetting is also available. See left for details.
IMPORTANT!:
Resetting the receiver (All reset) CLEARS all memory in-
formation and initializes all values in the receiver, includ-
ing TV channel skip setting.
➥ While pushing [VFO MHz] and [MR S.MW], turn the power
ON to reset the CPU.
