Important battery information
Important: The receiver is powered by a rechargeable battery.
Never use any charger or battery which is damaged.
The battery can be charged and discharged hundreds of times but it will eventually wear out .
When the operating time (talk-time and stand by time) is noticeably shorter than normal ,it is time to buy a new battery.
PROLONG THE BATTERY LIFE
Use the following guidelines to obtain the best performance from your battery:
Use the battery until it is fully discharged. With the receiver turned off, charge your new battery for 8 hours at the first time and 3~4 hours at the second and third time.
Note that a new battery?s full performance is achieved only after three complete charge and discharge cycles. Battery operation time may be less than the estimated times during the first charges. This condition is normal.
If the battery is completely empty, it may need to recharge a few minutes before you can switch the receiver on, a few minutes before you can switch the receiver on.
Important: when the phone?s battery is fully charged, be sure to disconnect the charger from the phone and the outlet
