Specific Absorption Rate (SAR)
Certification Information
Your wireless phone is a radio transmitter and
receiver. It is designed and manufactured not to
exceed the exposure limits for Radio Frequency (RF)
energy set by the Federal Communications
Commission (FCC) of the U.S. Government.
These FCC exposure limits are derived from the
recommendations of two expert organizations: the
National Council on Radiation Protection and
Measurement (NCRP) and the Institute of Electrical
and Electronics Engineers (IEEE).
In both cases, the recommendations were developed
by scientific and engineering experts drawn from
industry, government, and academia after extensive
reviews of the scientific literature related to the
biological effects of RF energy.
The 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 exposure 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 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.
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 exposure 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: 0.91 W/Kg.
•
Body-worn: 1.12 W/Kg.
2.4GHZ WLAN
•
Head: 0.28 W/Kg.
•
Body-worn: 0.16 W/Kg.
