Chapter 8 Health and Safety Information
Exposure to Radio Frequency (RF) Signals
Your wireless phone is a radio transmitter and receiver. It is designed and manufactured not to exceed
the emission limits for exposure to radio frequency (RF) energy set by the Federal Communications
Commission (FCC) for the U.S. Government. These limits are part of comprehensive guidelines and
establish permitted levels of RF energy for the general population. The guidelines are based on the
safety standards that were developed by independent scientific organizations through periodic and
thorough evaluation of scientific studies.
The standards include a substantial safety margin designed to assure the safety of all persons, regardless
of age and health.
The exposure standard for wireless phones employs a unit of measurement known as Specific
1
Absorption Rate (SAR). The SAR limit set by the FCC is 1.6 W/kg.
SAR tests are conducted using standard operating positions specified 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 of the phone.
Before a new model phone is available for sale to the public, it must be tested and certified by the FCC
to insure that it does not exceed the limit established by the government adopted requirement for safe
exposure. The tests are performed in positions and locations (e.g., at the ear and worn on body) as
required by the FCC for each model. While there may be differences between SAR levels of various
phones and at various positions, they all meet the government requirement.
The FCC has granted an Equipment Authorization for this model phone with all reported SAR levels
evaluated as in compliance with the FCC RF exposure guidelines. SAR information on this model
phone is on file with the FCC and can be found on the FCC website (http://www.fcc.gov/oet/fccid) after
searching the FCC ID printed in the label on the phone.
The highest SAR value for this model phone when tested for use at the ear is 1.49 W/kg; and when
worn on the body, as described in this user guide, is 1.303 W/kg.

In the U.S. and Canada, the SAR limit for mobile phones used by the public is 1.6 watts/kg (W/kg) averaged
over one gram of tissue. The standard incorporates a substantial margin of safety to give additional protection for
the public and to account for any variations in measurements.
