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.
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 the power source when it
is not in use. 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 because
the capacity and lifetime of the battery will be
reduced. Try to keep the battery at room temperature.
A phone with a hot or cold battery may not work
temporarily, even when the battery is fully charged. Li-
* The SAR limit for mobile phones used by the public is 2.0
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.
