Section 15: 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.
