Specific Absorption Rate
Specific Absorption Rate (SAR) is the unit of measurement for the amount of radio frequency
energy absorbed by the body when using a device. The SAR value is determined at the highest
certified power level in laboratory conditions, but the actual SAR level of the device while being
operated can be well below the value. This is because the device is designed to use the minimum
power required to reach the network. Before a device model is available for sale to the public,
it must be tested and certified by the Federal Communications Commission (FCC), ensuring that it
does not exceed the limit established by the government-adopted requirement for safe exposure.
The tests are performed in positions and locations (that is, at the ear and worn on the body) as
required by the FCC for each model. For body worn operation, this device has been tested and
meets FCC RF exposure guidelines when the handset is positioned a minimum of
5 mm from the
body with an accessory that contains no metal part. Use of other accessories may not ensure
compliance with FCC RF exposure guidelines. The SAR limit adopted by USA and Canada is 1.6
