Exposure to Radio-Frequency
Energy (SAR 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, so as
not to 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 SAR
(Specific Absorption Rate). The SAR limit
recommended by the EU Council is 2.0W/kg.*
* 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.
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 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, 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 (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.
