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 highest SAR value for this model phone when
tested for compliance against the standard was
0.892 W/kg. While there may be differences
between the SAR levels of various phones and
various positions, they all meet the EU
requirements for RF exposure.

Precautions When Using Batteries
Your phone is powered by a rechargeable Li-ion
standard battery.
• 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 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 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 Samsung-approved batteries and
recharge your battery only with Samsung-
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 its life.
• Extreme temperatures will affect the charging
capacity of your battery: it may require cooling or
warming first.
