Health and safety information
The highest SAR value for this model phone was 0.920
W/kg.
SAR tests are conducted using standard operating
positions with the phone transmitting at its highest
certified power level in all tested frequency bands.
Although the SAR is determined at the highest
certified power level, the actual SAR level of the phone
while operating can be well below the maximum value.
This is because the phone is designed to operate at
multiple power levels so as to use only the power
required to reach the network. In general, the closer
you are to a base station, the lower the power output
of the phone.
* The SAR limit for mobile phones used by the public is 1.6
watts/kilogram (W/kg) averaged over ten grams of body tis-
sue. 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.

Precautions when using batteries

• Never use a 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 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.
• If left unused, a fully charged battery will
discharge itself over time.
• Use only Samsung-approved batteries, and
recharge your battery only with Samsung-
approved chargers. Disconnect the charger from
