Specific Absorption Rate (SAR)
Information
Your wireless handset is a low power radio transmitter and receiver. When it is on, it receives and sends
out radio frequency (RF) signals. In August 1996, the Federal Communications Commission (FCC)
adopted radio frequency (RF) exposure guidelines with safety levels for hand-held wireless handsets.
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
These 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 handsets
employs a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit set by the
FCC is 1.6W/kg.
In the United States and Canada, the SAR limit for mobile handsets 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.
The FCC conducts tests for SAR using standard operating positions specified by the FCC with the handset
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 handset while operating can
be well below the maximum value. This is because the handset is designed to operate at multiple power
levels so that it uses only the power required to reach the network. Before a handset model is available
for sale to the public, the FCC must test and certify it to ensure that phones do not exceed the limit
established by the government-adopted requirement for safe exposure. The tests are performed in
positions and locations (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 handsets and at various positions, they all
meet the government requirement for safe exposure.
The FCC has granted an Equipment Authorization for this model handset with all reported SAR levels
evaluated in compliance with the FCC RF emission guidelines.
