Regulations and safety information
Specific Absorption Rate (SAR) information
Your wireless handheld portable telephone is a low power radio transmitter and
receiver. When it is on, it receives and also sends out radio frequency (RF) signals. In
August 1996, the Federal Communications Commissions (FCC) adopted RF
exposure guidelines with safety levels for handheld wireless phones. Those guidelines
are consistent with the safety standards previously set by both U.S. and international
standards bodies:
• ANSI C95.1 (1992) American National Standards Institute
• NCRP – Report 86 (1986) National Council on Radiation Protection and
Measurements
• ICNIRP (1996) International Commission on Non-Ionizing Radiation
Protection
• DHWC – Safety Code 6 Department of Health and Welfare Canada
Those standards 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 mobile phones employs a unit of
measurement known as the Specific Absorption Rate, or SAR. The SAR limit set by
the FCC is 1.6 W/kg
1
. Tests for SAR 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. Before a phone model 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 (for example, 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 for
safe exposure. The FCC has granted an Equipment Authorization for this model
phone with all reported SAR levels evaluated as in compliance with the FCC RF
emission guidelines. SAR information on this model phone is on file with the FCC
and can be found under the Display Grant section of http://www.fcc.gov/oet/fccid
1. In the United States 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.
