Health and Safety Information

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
0.845W/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
• 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.
• Do not leave the battery in hot or cold places,
such as in a car in summer or winter conditions,
as you 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 temporarily not work, 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-circuiting.
• Dispose of used batteries in accordance with local
regulations. Always recycle. Do not dispose of
batteries in a fire.
