Section 13: Health and Safety Information
This section outlines the safety precautions associated with using
your phone. These safety precautions should be followed to safely
use your phone.
Health and Safety Information
Exposure to Radio Frequency (RF) Signals
Certification Information (SAR)
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
Counsel 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
