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.

OPERATING NOTES

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.

■ 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.

Battery pack installation

q Remove the battery cover from the receiver. w Remove the supplied battery spacer for R6 (AA) size bat-

tery use.

e Install the Li-Ion battery pack (BP-206).

• Be sure to observe the correct direction.

• Charge the Li-Ion battery pack before use.

•Battery pack installation

•Battery pack removal

Page 22

■ Caution

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.

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 completely 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 battery 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, because, a slight current still follows in the CP-18A/E and the vehicle’s battery will become exhausted.

■ Battery charging

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.

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 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.

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.

Recommendation:

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

Fuse 5 A

Shorten or remove the antenna.

Turn power OFF.

SCAN OPERATION

■ Auto-memory write scan

This scan is useful for searching a speciﬁed frequency range and automatically storing busy frequencies into memory channels. The auto-memory write scan is performed with any VFO scan types (ALL, BAND, PROG).

qSelect VFO mode with [VFO MHz]. wPush and hold [MODE SCAN] to enter scanning type se-

lection condition.

eRotate [R-DIAL] to select the desired scanning type.

• “ALL” for full scan; “BAND” for band scan, “PROG-xx” for programmed scan (xx= 0 to 24; programmed scan edges numbers only displayed)

rRelease [MODE SCAN] to start the scan. tPush [MR S.MW] to turn the automatic memory write func-

tion ON and OFF.

•“µµ” indicator blinks.

yPush [DUALWATCH] to stop the scan.

During auto-memory write scanning:

• When a signal is received, scan pauses and the frequency is stored into auto-memory write channel group (åå000 –

• Scan resumes after frequency storing.

• When all channels are stored, the scan is cancelled automatically and 1 long beep sounds.

Recalling the stored frequencies:

qPush [MR S.MW] several times to select the auto-memory

write channel group.

wRotate [R-DIAL] to select the desired channel.

Clearing the stored frequencies:

qSelect the auto-memory write channel group. wPush [5 SKIP] for 1 sec. to clear the all channels contents.

•1 short and 1 long beeps sound.

NOTE: The auto-memory write channel contents CANNOT be cleared by an independent channel. Thus it is a good idea to copy the contents into regular memory channel.
