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) of 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 through 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 Absorption Rate (SAR). The SAR limit
recommended by the FCC is 1.6W/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 to the FCC 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 the body) as required by the FCC for each model. While there
may be differences between the 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 under the Display Grant section of http:/
* 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.
