Using the Batteries
Your phone is powered by a rechargeable Li-ion
standard battery.
Precautions When Using Batteries
• Never use any charger or battery that is damaged
in any way.
• Use the battery only for its 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 times depend 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.

succession, the SIM card cannot be used anymore.

PUK2
The PUK2, supplied with some SIM cards, is required
to change a blocked PIN2.

succession, you cannot use the functions requiring
the PIN2. Contact your service provider for a new
card.
