3 BATTERY CHARGING ■ Caution (for the supplied BP-264 Ni-MH battery pack) 1 • R DANGER! NEVER short terminals (or charging terminals) of the battery pack. Also, current may flow into nearby metal objects such as a necklace, so be careful when placing battery packs (or the transceiver) in handbags, etc. Simply carrying with or placing near metal objects such as a necklace, etc. may cause shorting. This may damage not only the battery pack, but also the transceiver. • R DANGER! NEVER incinerate used battery packs. Internal battery gas may cause an explosion. • R DANGER! NEVER immerse the battery pack in water. • C lean the battery terminals to avoid rust or misscontact. 2 • Keep battery terminals clean. It's a good idea to clean bat- 3 tery terminals once a week. 4 • If your Ni-MH battery pack seems to have no capacity, even after being charged, completely discharge it by leaving the 5 power ON overnight. Then, fully charge the battery pack again. If the battery pack still does not retain a charge (or only very lit- 6 tle charge), a new battery pack must be purchased. 7 Prior to using the transceiver for the first time, the battery pack must be fully charged for optimum life and operation. 8 If the battery pack becomes wet, be sure to wipe it dry BEFORE attaching it to the transceiver. • C AUTION: Always use the battery within the specified temperature range, -5˚C to +60˚C (+23˚F to +140˚F). Using • Recommended temperature range for charging: 9 between 0°C and +45°C for the regular charge by the transceiver. 10 or between +10°C and +40°C for the rapid charge with the 11 the battery out of its specified temperature range will reduce the battery's performance and battery life. • C AUTION: Shorter battery life could occur if the battery is BP-191. 12 • Use the supplied charger (BC-167S) or optional charger (BC-191) only. NEVER use other manufacturers' chargers. 13 left completely discharged, or in an excessive temperature environment (above +55˚C; +131˚F) for an extended period of time. If the battery must be left unused for a long time, it must be detached from the radio after charging. Keep it safely in a cool dry place at the following temperature range: -20˚C to +45˚C (-4˚F to +113˚F) (up to a month) -20˚C to +35˚C (-4˚F to +95˚F) (up to six months) -20˚C to +25˚C (-4˚F to +77˚F) (up to a year*) * We recommend charging the battery pack every 6 months. • The battery pack contains a rechargeable battery. 14 Charge the battery pack before first operating the transceiver, or when the battery pack becomes exhausted. 15 If you want to prolong the battery life, the following points 16 should be observed: - Avoid over charging. 17 - Use the battery pack until it becomes almost completely 18 exhausted, under normal conditions. We recommend bat- tery charging after transmitting becomes impossible. 19
