Certification information (SAR)
This mobile device meets international guidelines for exposure to
radio waves.
Your mobile device is a radio transmitter and receiver. It is designed not
to exceed the limits for exposure to radio waves (radio frequency
electromagnetic fields), recommended by international guidelines from
the independent scientific organization ICNIRP. These guidelines
incorporate substantial safety margins that are intended to assure the
protection of all persons regardless of age and health.
The exposure guidelines are based on the Specific Absorption Rate (SAR),
which is an expression of the amount of radio frequency (RF) power
deposited in the head or body when the device is transmitting. The
ICNIRP SAR limit for mobile devices is 2.0 W/kg averaged over 10 grams
of tissue.
SAR tests are carried out with the device in standard operating positions,
transmitting at its highest certified power level, in all its frequency bands.
The maximum recorded SAR values for this device are:
