INSTRUCTION MANUALVHF TRANSCEIVERiV8 This device complies with Part 15 of the FCC rules. Oper-ation is subject to the following two conditions: (1) This de-vice may not cause harmful interference, and (2) thisdevice must accept any interference received, including in-terference that may cause undesired operation.1-1-32 Kamiminami, Hirano-ku, Osaka 547-0003 JapanA-6043H-1EXPrinted in Japan© 2001 Icom Inc.Count on us!
iiiSAFETY TRAINING INFORMATIONCAUTIONTo 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 “PTT”switch.• 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.• ALWAYS keep the antenna at least 2.5 cm (1 inch) away fromthe body when transmitting and only use the Icom belt-clipswhich listed in this manual when attaching the radio to yourbelt, etc. To provide the recipients of your transmission thebest sound quality, hold the antenna at least 5 cm (2 inches)from 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.

vivPRECAUTIONRWARNING! 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, higher fuse values will not give any pro-tection against such accidents and the transceiver will be ru-ined.NEVER attempt to charge alkaline or dry cell batteries. Be-ware that external DC power connections will charge batteriesinside the battery case. This will damage not only the batterycase but also the transceiver.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 –10°C (+14°F) or above +60°C(+140°F).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.

NEVER short the terminals of the battery pack (orcharging 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. It’s 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).DDRecycling information (U.S.A. only)The product that you have purchased contains arechargeable battery.
