THIS DEVICE MEETS
INTERNATIONAL GUIDELINES FOR
EXPOSURE TO RADIO WAVES
Your mobile device is a radio
transmitter and receiver. It is
designed and manufactured not to
exceed the limits for exposure to
radio frequency (RF) recommended
by international guidelines
(ICNIRP). 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 periodic and thorough
evaluation of scientific studies. The
guidelines include a substantial
safety margin designed to assure
the safety of all persons, regardless
of age or health.
The exposure standard for
mobile devices employs a unit
of measurement known as the
Specific Absorption Rate, or
SAR. The SAR limit stated in the
international guidelines 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. Although
the SAR is determined at the
highest certified power level, the
actual SAR of the device while
operating can be well below the
maximum value. This is because
the device 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,
