To avoid damage and comply with warranty terms, charge the battery using only an original RCA charger, exactly as described in the charger user guide. When the chargers LED illuminates red, it is an indication that the battery is being correctly charged. When the LED illuminates green, the battery charge is complete. Note: Charge a new battery 12 to 14 hours before initial use for best performance. Maximum battery capacity is normally achieved after two or three full charge / discharge cycles. Image C Caution: To reduce the risk of injury, use only batteries specified by RCA Communications Systems. To avoid risk of personal injury, do not dispose of batteries in a fire. -
Dispose of batteries according to local recycling regulations. Do not dispose as household waste. Never attempt to disassemble the battery. When charging a battery, keep it at a temperature between 41F ~
104F (5C ~ 40C) to ensure a full charge. Temperatures outside this range significantly reduce battery life. The operating time (talk-
time and standby time) is noticeably shorter than normal, replace the battery. Before charging a battery attached to a radio, turn the radio off to ensure a full charge. Never leave a radio on while in the charger, as it can damage both the battery and the radio; the charger is not a radio stand. 3 charging. The battery will eventually weaken. When the operating time (talk-
time and standby time) becomes noticeably shorter than normal, replace the battery. Battery performance greatly decreases at temperatures below -4F
(-20C). Having a spare battery is always necessary in extremely cold environments. A cold battery may work again when it returns to room temperature, so keep it for later use. Dust on the battery contact may cause the battery not to work or charge properly. Use a clean dry cloth to wipe it before attaching the battery to the radio. Batteries with damaged contacts can be extremely dangerous. Any battery with damage to one or more contacts should be replaced immediately and not used under any circumstances. Battery Storage 1. Fully charge the battery before storing it for an extended period of time to avoid battery damage due to over-discharge. 2. Recharge a battery after three months storage to avoid reduced battery capacity due to over-discharge. 3. When storing a battery, keep it in a dry place at room temperature.
