59 Health and safety information
SAR certification information
This phone meets European Union (EU)
requirements concerning exposure to radio waves.
Your mobile phone is a radio transmitter and
receiver. It is designed and manufactured to not
exceed the limits for exposure to radio-frequency
(RF) energy, as recommended by the EU Council.
These limits are part of comprehensive guidelines
and establish permitted levels of RF energy for the
general population. The guidelines were developed
by independent scientific organisations through the
periodic and thorough evaluation of scientific
studies. The limits include a substantial safety
margin designed to ensure the safety of all persons,
regardless of age and health.
The exposure standard for mobile phones employs
a unit of measurement known as Specific
Absorption Rate (SAR). The SAR limit recommended
by the EU Council is 2.0 W/kg. *
The highest SAR value for this model phone was
0.245 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.
Before a new model phone is available for sale to
the public, compliance with the European R&TTE
Directive must be shown. This directive includes as
one of its essential requirements the protection of
the health and safety of the user and any other
person.
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 or Bang & Olufsen approved
batteries, and recharge your battery only with
Samsung or Bang & Olufsen 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.
- Dispose of used batteries in accordance with
local regulations. Always recycle. Do not dispose
of batteries in a fire.
* The SAR limit for mobile phones used by the public is
2.0 watts/kilogram (W/kg) averaged over ten grams of
body tissue. 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.
