209BATTERY CHARGING■Battery chargingPrior to using the transceiver for the first time, the batterypack must be fully charged for optimum life and operation.CAUTION: To avoid damage to the transceiver, turn it OFFwhile charging.•Recommended temperature range for charging:+10°C to +40°C (+50°F to +104°F)•Use the supplied charger (BC-152) only. NEVER use an-other manufacturer’s charger.■CautionNEVER incinerate used battery packs. Internal battery gasmay cause an explosion.NEVER immerse the battery pack in water. If the battery packbecomes wet, be sure to wipe it dry immediately (particularlythe battery terminals) BEFORE attaching it to the transceiver.Otherwise, the terminals will become corroded, or cause con-nection failure, etc.NEVER short the terminals of the battery pack. Also, currentmay flow into nearby metal objects, such as a necklace, etc.Therefore, be careful when carrying with, or placing nearmetal objects, carrying in handbags, etc.AVOID leaving the battery pack in a fully charged, or com-pletely discharged condition for long time. It causes shorterbattery life. In case of leaving the battery pack unused for along time, it must be kept safely after discharge, or use thebattery until the battery indicator shows the middle level, thenremove it from the transceiver.If your battery pack seems to have no capacity even afterbeing charged, completely discharge it by leaving the powerON overnight. Then, fully charge the battery pack again. If thebattery pack still does not retain a charge (or very little), anew battery pack must be purchased.Recommendation:Charge the supplied battery pack for a maximum ofup to 8 hours. Li-Ion batteries are different from Ni-Cd batteries in that it is not necessary to completelycharge and discharge them to prolong the battery life.Therefore, charge the battery in intervals, and not forextended periods is recommended.IC-M88-draft.qxd 02.9.26 2:44 PM Page 20 (1,1)
