BATTERY CHARGING 2 • C AUTION: Shorter battery life could occur if the batteries are left completely discharged, or in an excessive temperature environment (above +55˚C; +131˚F) for an extended period of time. If the batteries must be left unused for a long time, they must be detached from the receiver after charging. Keep them 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 batteries every 6 months. • If your Ni-MH batteries seem to have no capacity, even after being charged, completely discharge them by leaving the power ON overnight. Then, fully charge the batteries again. If the batteries still do not retain a charge (or only very little charge), a new batteries must be purchased. Prior to using the receiver for the first time, the batteries must be fully charged for optimum life and operation. • The supplied batteries are rechargeable batteries. Charge the batteries before first operating the receiver, or when the batteries become exhausted. If you want to prolong the battery life, the following points should be observed: - Avoid over charging. - Use the batteries until it becomes almost completely exhausted, under normal conditions. D Charging caution 2 • R WARNING! NEVER charge alkaline batteries. The receiver can charge only the Ni-MH batteries (1.2 V, 1400 mAH typical). Other types of rechargeable battery, such as Ni-Cd or Li-Ion cannot be charged. • A VOID over charging- The installed rechargeable batteries can be charged during operation when the AC adapter or the cigarette lighter cable is connected. To prevent over charging, the IC-R6 has charging timer that automatically disconnecting* the charging line electronically after 15 hours from charging. However, the charging timer will reset and start charging again when disconnect then reconnecting the AC adapter or CP-18A/E more than 1 minute interval. * W hen the "CHARGE" setting in the Set mode is set to "CHG2 (default)," the receiver continues to trickle charge after 15 hours have past. • Recommended temperature range for charging: between 0°C (+32˚F) and +40°C (+104˚F) by the receiver. • Use the BC-196SA/SD/BC-153SC AC adapter or CP-18A/ E cigarette liter cable only. NEVER use other manufacturers' chargers. • The external DC power supply voltage must be between 12-16 V to charge the batteries and for operation when using an optional CP-18A/E. • If the battery icons (" " and " ") disappear only 1 minute after connecting to the DC power supply, the batteries may have problem. In this case, contact your Icom dealer/distributor, or purchase new batteries.
