USING BATTERIES
Precautions when using batteries
• Never use any charger or battery that is damaged in any way.
• Use the battery only for intended purpose.
• No indication of charging: When you start charging a battery that is empty or a
battery that has not been used for a long time, it may take up to 30 minutes before
the battery icon appears in the display.
• 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. When charging
after complete discharge, the phone will not display anything for about 30 minutes.
• 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,
since overcharging may shorten the battery life.
• Extreme temperatures will affect the charging capacity of your battery: it may require
cooling or warming first.
• Do not leave the battery in hot or cold places, such as in a car in summer or winter
conditions, as it will reduce the capacity and lifetime of the battery. Always try to keep
the battery at room temperature. A phone with a hot or cold battery may not work
temporarily, even when the battery is fully charged. Li-ion batteries are particularly
affected by temperatures below 0°C (32°F).
• Do not short-circuit the battery. Accidental short-circuiting can occur when a metallic
object (coin, clip or pen) causes a direct connection between the + and – terminals of
the battery (metal strips on the battery), for example, when you carry a spare battery
in a pocket or bag.
• Short-circuiting the terminals may damage the battery or the object causing the
short-circuit.
