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
