Specific Absorption Rate (SAR)
Your wireless device is a radio transmitter and receiver. It is designed not
to exceed the limits for exposure to radio waves recommended by
international guidelines. These guidelines were developed by the
independent scientific organization ICNIRP and include safety margins
designed to assure the protection of all persons, regardless of age and
health.
The guidelines use a unit of measurement known as the Specific
Absorption Rate, or SAR. The SAR limit for wireless devices is 2.0 W/kg
and the highest SAR value for this device when tested complied with this
limit.
Body Worn Operation
