Health and safety
The device meets international guidelines for exposure to
radio waves.
Your device is a radio transmitter and receiver. It's
designed not to exceed the limits for exposure to radio
waves recommended by international guidelines. The
guidelines were developed by the International
Commission on Non-lonizing Radiation Protection
(ICNIRP), an independent technical standards body, and
include margins designed to assure the safety of all
persons, regardless of age and health. These guidelines
use a unit of measurement known as Specific Absorption
Rate (SAR). The SAR limit for mobile devices is 2.0
W/Kg (Head, Body-worn), 4.0 W/Kg (Limbs) and the
highest SAR value for this device when tested for use at
the head was 1.129 W/Kg, when tested for use at the
body-worn was 1.129 W/Kg and when tested for use at
7
