The RF exposure limit set by the FCC for wireless mobile
phones employs a unit of measurement known as the
Specific Absorption Rate (SAR). The SAR is a measure of
the rate of absorption of RF energy by the human body
expressed in units of watts per kilogram (W/kg). The FCC
requires wireless phones to comply with a safety limit of
1.6 watts per kilogram (1.6 W/kg).
The FCC SAR limit incorporates a substantial margin of
safety to give additional protection to the public and to
account for any variations in measurements.
SAR tests are conducted using standard operating
positions accepted by the FCC with the phone 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 level of the phone
while operating can be well below the maximum reported
value. This is because the phone 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
wireless base station antenna, the lower the power output
of the phone.
Before a new model phone is available for sale to the
public, it must be tested and certified to the FCC that it
does not exceed the SAR limit established by the FCC.
Tests for each model phone are performed in positions
and locations (e.g. at the ear and worn on the body) as
required by the FCC. For body-worn operation, this phone
has been tested and meets FCC RF exposure guidelines
when used with an accessory that contains no metal and
that positions the mobile device a minimum of 1.
0 cm
from the body. Use of other accessories may not ensure
compliance with FCC RF exposure guidelines. The FCC
has granted an Equipment Authorization for this mobile
device with all reported SAR levels evaluated as in
compliance with the FCC RF exposure guidelines.
