iSAFETY TRAINING INFORMATION

CAUTIONTo ensure that your exposure to RF electromagnetic en-ergy is within the FCC allowable limits, always adhere tothe following guidelines:

DO NOT operate the radio without a proper antenna attached,as this may damage the radio and may also cause you to ex-ceed FCC RF exposure limits. A proper antenna is the an-tenna supplied with this radio by the manufacturer or anantenna specifically authorized by the manufacturer for usewith this radio.

DO NOT transmit for more than 50% of total radio use time(50% duty cycle). Transmitting more than 50% of the timecan cause FCC RF exposure compliance requirements to beexceeded. The radio is transmitting when the TX indicator islit. You can cause the radio to transmit by pressing the PTTswitch.

ALWAYS use Icom authorized accessories (antennas, batter-ies, belt clips, speaker/mics, etc.). Use of unauthorized acces-sories can cause the FCC RF exposure compliancerequirements to be exceeded.


ii

ALWAYS keep the antenna at least 2.5 cm (1 inch) away fromthe body when transmitting, and only use the Icom belt-clipswhich are listed in this manual when attaching the radio toyour belt, etc. To provide the recipients of your transmissionthe best sound quality, hold the antenna at least 5 cm (2inches) from your mouth, and slightly off to one side.

The information listed above provides the user with the in-formation needed to make him or her aware of RF expo-sure, and what to do to assure that this radio operateswithin the FCC RF exposure limits of this radio. Electro-magnetic Interference/Compatibility. During transmissions,your Icom radio generates RF energy that can possiblycause interference with other devices or systems. To avoidsuch interference, turn off the radio in areas where signsare posted to do so. DO NOT operate the transmitter inareas that are sensitive to electromagnetic radiation suchas hospitals, aircraft, and blasting sites.

vPRECAUTIONRWARNING! NEVER hold the transceiver so that theantenna is very close to, or touching exposed parts of the body,especially the face or eyes, while transmitting. The transceiverwill perform best if the microphone is 5 to 10 cm (2 to 4 in) awayfrom the lips and the transceiver is vertical.

RWARNING! NEVER operate the transceiver with aheadset or other audio accessories at high volume levels. Hear-ing experts advise against continuous high volume operation. Ifyou experience a ringing in your ears, reduce the volume or dis-continue use.

NEVER connect the transceiver to a power source that is DCfused at more than 5 A. Accidental reverse connection will beprotected by this fuse, but higher fuse values will not give anyprotection against such accidents and the transceiver will be ru-ined.

NEVER attempt to charge alkaline or dry cell batteries. Be aware that external DC power connections will charge batteriesinside the battery case. This will damage not only the batterycase but also the transceiver.


vi

DO NOT push the PTT when not actually desiring to trans-mit.

Place unit in a secure place to avoid inadvertent use by chil-dren.

DO NOT operate the transceiver near unshielded electricalblasting caps or in an explosive atmosphere.

AVOID using or placing the transceiver in direct sunlight or inareas with temperatures below 10C (+14F) or above +60C(+140F).The use of non-Icom battery packs/chargers may impair trans-ceiver performance and invalidate the warranty.

Even when the transceiver power is OFF, a slight current stillflows in the circuits. Remove the battery pack or case from thetransceiver when not using it for a long time. Otherwise, the bat-tery pack or installed Ni-Cd batteries will become exhausted.

For USA only:Caution: Changes or modifications to this transceiver, not ex-pressly approved by Icom Inc., could void your authority to op-erate this transceiver under FCC regulations.

3 BATTERY PACKS Battery caution CAUTION! NEVER short the terminals of the battery pack (or

charging terminals of the transceiver). Also, current may flow intonearby metal objects such as a necklace, so be careful when plac-ing battery packs (or the transceiver) in handbags, etc.Simply carrying with or placing near metal objects such as a neck-lace, etc. causes shorting. This will damage not only the batterypack, but also the transceiver.

NEVER incinerate used battery packs. Internal battery gas maycause an explosion.

NEVER immerse the battery pack in water. If the battery pack be-comes wet, be sure to wipe it dry BEFORE attaching it to thetransceiver.

Clean the battery terminals to avoid rust or miss contact. Keep battery contacts clean. Its a good idea to clean battery ter-

minals once a week.

If your battery pack seems to have no capacity even after beingcharged, completely discharge it by leaving the power ONovernight. Then, fully charge the battery pack again. If the batterypack still does not retain a charge (or only very little charge), a newbattery pack must be purchased (p. 59).

DD Recycling information (U.S.A. only)The product that you have purchased contains arechargeable battery. The battery is recyclable. Atthe end of its life, under various state and locallaws, it may be illegal to dispose of this battery intothe municipal waste stream. Call 1-800-822-8837

for battery recycling options in your area or contact your dealer.


Battery chargingD Regular charging

with the BC-146The optional BC-146 providesregular charging of an optionalbattery pack with/withouttransceiver. The following isadditionally required: An optional AC adaptor.(An AD-99 is supplied with BC-146.)

D About AD-99Attach the spacer (Spacer B/C)to the adaptor (Spacer A) withorientation as illustrated in the di-agram below. Attach the spacer (Spacer B/C) to

the adaptor with the orientation ofthe stamp pointing up.

When removing the spacer(Spacer B/C), Push the notchcarefully with your finger to re-move the spacer (Spacer B/C)from the adapter (Spacer A).

R CAUTION!DO NOT push or force the notch with a screw driver, etc., to remove it.DO NOT bend the notch when the adapter and spacer are not joinedtogether. This will cause weakening of the notch plastic.

Both cases may break the notch and it may not be able to be reattached.12

3BATTERY PACKS Charging NOTEPrior to using the transceiver for the first time, the battery pack mustbe fully charged for optimum life and operation. Recommended temperature range for charging: +10C to +40C (50F to 140F).

Use the supplied charger or optional charger (BC-144/BC-121 forrapid charging, BC-146 for regular charging) only. NEVER use othermanufacturers chargers.

The optional BP-222, BP-209 or BP-210 battery packs includerechargeable Ni-Cd (Ni-MH: BP-210) batteries and can be chargedapprox. 300 times. Charge the battery pack before first operatingthe transceiver or when the battery pack becomes exhausted.If you want to charge the battery pack more than 300 times, the fol-lowing points should be observed:

Avoid over charging. The charging period should be less than 24 hours.

Use the battery until it becomes almost completely exhausted undernormal conditions. We recommend battery charging after transmittingbecomes impossible.

DD Battery pack lifeWhen the operating period becomes extremely short even aftercharging the battery pack fully, a new battery pack is needed.


15

3 BATTERY PACKS Battery case (optional for some versions)When using a BP-208 BATTERY CASE attached to the transceiver,install 6 AA (R6) size alkaline batteries as illustrated below.

DD CAUTIONS Use ALKALINE batteries only. Make sure all battery cells are the same brand, type and ca-

pacity. Never mix old and new batteries.Either of the above may cause a fire hazard or damage thetransceiver if ignored.

Never incinerate used battery cells since internal battery gasmay cause them to rupture.

Never expose a detached battery case to water.If the battery case gets wet, be sure to wipe it dry before use.
