Information on Specific Absorption Rate (SAR) values
To communicate with the network, mobile phones emit low levels of
radio waves (also known as radiofrequency or 'RF' energy) when being
used. Governments around the world have adopted comprehensive
international safety guidelines, developed by independent scientific
organizations, governing the exposure to RF energy. Mobile phones are
designed to operate within these stringent limits.

What is SAR?
SAR stands for Specific Absorption Rate, which is the unit of
measurement for the amount of RF energy absorbed by the body when
using a mobile phone.  The SAR is determined at the highest certified
power level in laboratory conditions.  However, the actual SAR level
of the phone while operating can be well below this value.   This is
because the phone is designed to use the minimum power required to
reach the network.  Therefore, the closer you are to a base station,
the more likely it is that the actual SAR level will be lower.

Does a lower SAR mean that a phone is safer?
No. Variations in SAR do not mean that there are variations in safety.
While there may be differences in SAR levels among phone models, all
mobile phones must meet RF exposure guidelines.
