As SAR is measured utilizing the devices highest
transmitting power the actual SAR of this device
while operating is typically below that indicated
above. This is due to automatic changes to the
power level of the device to ensure it only uses the
minimum level required to reach the network.
The World Health Organization has stated that
present scientific information does not indicate the
need for any special precautions for the use of
mobile devices. They note that if you want to reduce
your exposure then you can do so by limiting the
length of calls or using a 'hands-free' device to keep
the mobile phone away from the head and body.
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-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 like a
coin, clip or pen causes a direct connection
between the + and – terminals of the battery
(metal strips on the battery). For example, do
not carry a spare battery in a pocket or bag
where the battery may contact metal objects.
Short-circuiting the terminals may damage the
battery or the object causing the short-circuiting.
