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:
Maximum SAR value
When held against 0.64 W/kg over 10g
the head
When operated at a 0.20 W/kg over 10g
separation distance
of 1.5 centimetres
(5/8 inch) from the
body
Your mobile device is also designed to meet the United States Federal
Communications Commission (FCC) and Industry Canada SAR (IC)
guidelines. FCC ratings for your device and more information on SAR
