Specific Absorption Rate (ICNIRP)
YOUR DEVICE MEETS INTERNATIONAL
GUIDELINES FOR EXPOSURE TO RADIO WAVES.
Your 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.
The guidelines were developed by an independent
scientific organization (ICNIRP) and include a
substantial safety margin designed to assure the
safety of all persons, regardless of age and health.
The radio wave exposure guidelines use a unit of
measurement known as the Specific Absorption
Rate, or SAR. The Europe 10g SAR limit for mobile
devices is 2.0 W/kg. Tests for SAR are conducted
using standard operating positions with the device
transmitting at its highest certified power level in
all tested frequency bands. The highest SAR values
under the ICNIRP guidelines for your device are as
follows:
Maximum body-worn SAR with 0 mm separation
distance: 0.719 W/kg
During use, the actual SAR values for your device
are usually well below the values stated. This is
because, for purposes of system efficiency and to
minimize interference on the network, the
operating power of your mobile device is
automatically decreased when full power is not
needed for the data connection. The lower the
power output of the device, the lower its SAR
value.
If you are interested in further reducing your RF
exposure then you can easily do so by limiting your
usage or simply keeping the device away from the
body.
