337BATTERY 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 thepower OFF while charging.• Recommended temperature range for charging:+10°C to +40°C• Use the specified chargers (BC-119N, BC-121N and BC-160). NEVER use another manufacture’s charger.• Use the specified AC adapter. NEVER use another manu-facture’s adapter. Battery cautionR DANGER Charge the specified Icom batteries only.Only tested and approved for use with genuine Icom batter-ies. Fire and/or explosion may occur when a third party bat-tery pack or counterfeit product is charged.CAUTION! NEVER insert battery pack/transceiver (with thebattery pack attached) in a wet or soiled condition into thecharger. This may result in corrosion of the charger terminalsor damage to the charger. The charger is not waterproof andwater can easily get into it.NEVER incinerate used battery packs. Internal battery gasmay cause an explosion.NEVER immerse the battery pack in water. If the batterypack becomes wet, be sure to wipe it dry BEFORE attachingit to the transceiver.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 completelydischarged condition for long time. It causes shorter battery life.In case of leaving the battery pack unused for a long time, itmust be kept safely after discharge, or use the battery until thebattery indicator appears, then remove it from the transceiver.If your battery pack seems to have no capacity even afterbeing charged, fully charge the battery pack again. If the bat-teries still do not retain a charge (or very little), new batterypack must be purchased.Recommendation:Charge the supplied battery pack for a maximum ofup to 10 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, charging the battery in intervals, and notfor extended periods is recommended.
