CAUTION To ensure that your exposure to RF electromagnetic en- ergy is within the FCC allowable limits, always adhere to the 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 an antenna specifically authorized by the manufacturer for use with this radio. • DO NOT transmit for more than 50% of total radio use time (“50% duty cycle”). Transmitting more than 50% of the time can cause FCC RF exposure compliance requirements to be exceeded. The radio is transmitting when the “TX indicator” is lit. 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 compliance requirements to be exceeded. • ALWAYS keep the antenna at least 2.5 cm (1 inch) away from the body when transmitting and only use the Icom belt-clips which listed in this manual when attaching the radio to your belt, etc. To provide the recipients of your transmission the best 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 operates within the FCC RF exposure limits of this radio. Electro- magnetic Interference/Compatibility During transmissions, your Icom radio generates RF energy that can possibly cause interference with other devices or systems. To avoid such interference, turn off the radio in areas where signs are posted to do so. DO NOT operate the transmitter in areas that are sensitive to electromagnetic radiation such as hospitals, aircraft, and blasting sites.

antenna is very close to, or touching exposed parts of the body, especially the face or eyes, while transmitting. The transceiver will perform best if the microphone is 5 to 10 cm (2 to 4 in) away from the lips and the transceiver is vertical. RWARNING! NEVER operate the transceiver with a headset or other audio accessories at high volume levels. Hear- ing experts advise against continuous high volume operation. If you experience a ringing in your ears, reduce the volume or dis- continue use. NEVER connect the transceiver to a power source that is DC fused at more than 5 A. Accidental reverse connection will be protected 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 batteries inside the battery case. This will damage not only the battery case 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 electrical blasting caps or in an explosive atmosphere. AVOID using or placing the transceiver in direct sunlight or in areas 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 still flows in the circuits. Remove the battery pack or case from the transceiver 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.

D Regular charging with the BC-146 The optional BC-146 provides regular charging of optional battery pack with/without transceiver. The following is additionally required: • An optional AC adaptor. D About AD-99 Attach the spacer (Spacer B/C) to the adaptor (Spacer A) with ori- entation as illustrated in the diagram below. • Attach the spacer (Spacer B/C) to the adaptor with the orientation of the stamp “ ” pointing up. 11 3 BATTERY PACKS 12 3 BATTERY PACKS ‘ Battery caution • CAUTION! NEVER short the terminals of the battery pack (or charging terminals of the transceiver). Also, current may flow into nearby 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 battery pack, but also the transceiver. • NEVER incinerate used battery packs. Internal battery gas may cause 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 the transceiver. • 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 being charged, completely discharge it by leaving the power ON overnight. Then, fully charge the battery pack again. If the battery pack still does not retain a charge (or only very little charge), a new battery pack must be purchased (p. 59). D Recycling information (U.S.A. only) The product that you have purchased contains a rechargeable battery. The battery is recyclable. At the end of its life, under various state and local laws, it may be illegal to dispose of this battery into the municipal waste stream. Call 1-800-822-8837 for battery recycling options in your area or contact your dealer. BC-146 + AD-99 Check orientation for correct charging. (Insert together with AD-99.) Turn power OFF. Check orientation and Spacer A Spacer B/C

Prior to using the transceiver for the first time, the battery pack must be fully charged for optimum life and operation. • Recommended temperature range for charging: +10°C to +40°C (50°F to 140°F). • Use the supplied charger or optional charger (BC-144/BC-121 for rapid charging, BC-146 for regular charging) only. NEVER use other manufacturers’ chargers. The optional BP-222, BP-209 or BP-210 battery packs include rechargeable Ni-Cd (Ni-MH: BP-210) batteries and can be charged approx. 300 times. Charge the battery pack before first operating the 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 under normal conditions. We recommend battery charging after transmitting becomes impossible. D Battery pack life When the operating period becomes extremely short even after charging the battery pack fully, a new battery pack is needed. D Rapid charging with the BC-144 (#11) The optional BC-144 (#11) provides rapid charging of op- tional battery packs. The following are additionally required: • An AC adaptor (may be sup- plied with the BC-144 de- pending on version). D Rapid charging with the BC-121+AD-94 (#11) The optional BC-121 allows up to 6 battery packs to be charged si- multaneously. The following are additionally required. • Six AD-94 (#11). • An AC adaptor (may be supplied with the BC-121 depending on version). MULTI-CHARGER AC adapter (purchased separately) Charge indicator (each indicator functions independently) Turn power OFF. Check orientation for correct charging. (Insert together with AD-99.)
