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 1.5
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 phone with all reported SAR levels
evaluated as in compliance with the FCC RF
exposure guidelines. The maximum SAR values
for this model phone as reported to the FCC are:
•
Head: 0.34 W/kg.
•
Body: 0.67 W/kg.
SAR information on this and other model phones
can be accessed online on the FCC's website
.
To find information that pertains to a particular
model phone, this site uses the phone FCC ID
number which is usually printed somewhere on
the case of the phone. Sometimes it may be
necessary to remove the battery pack to find the
number. Once you have the FCC ID number for a
particular phone, follow the instructions on the
website and it should provide values for typical
or maximum SAR for a particular phone.
Additional SAR information can also be obtained
