Using the Batteries
Precautions When Using Batteries
 Never use any charger or battery that is damaged in any
way.
 Use the battery only for intended purpose.
 If you use the phone near the network’s base station, it
uses less power; talk and standby times are greatly
affected by the signal strength on the cellular network
and the parameters set by the network operator.
 Battery charging time depends on the remaining battery
charge and the type of battery and charger used. The
battery can be charged and discharged hundreds of
times, but it will gradually wear out. When the
operation time (talk time and standby time) is noticeably
shorter than normal, it is time to buy a new battery.
 If left unused, a fully charged battery will discharge itself
over time.
 Use only approved chargers. When a charger is not in
use, disconnect it from the power source. Do not leave
the battery connected to a charger for more than a week,
