A. The SAR limit for mobile phones used by the public is
1.6
watts/kilogram (W/kg) averaged over ten grams of
body tissue. The limit incorporates a substantial margin
of safety to give additional protection for the public and
to account for any variations in measurements. The
SAR values may vary, depending on national reporting
requirements and the network band.
1. 3 Battery Use
Use only approved batteries. Use of any unauthorized accessories
could damage you and your phone and may be dangerous. If
jewelry, keys, beaded chains, or other conductive materials touch
exposed battery terminals, this could complete an electrical circuit
(short circuit), become very hot, and could cause damage or injury.
Never use a charger or battery that is damaged.
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 time 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,
the type of battery, and the charger used. The battery can be
charged and discharged hundreds of times, but it will gradually
wear out. When the operation time is noticeably shorter than
normal, it is time to buy a new battery.
