15Regulations and safety informationSpecific Absorption Rate (SAR) informationYour wireless handheld portable telephone is a low power radio transmitter andreceiver. When it is on, it receives and also sends out radio frequency (RF) signals. InAugust 1996, the Federal Communications Commissions (FCC) adopted RFexposure guidelines with safety levels for handheld wireless phones. Those guidelinesare consistent with the safety standards previously set by both U.S. and internationalstandards bodies:• ANSI C95.1 (1992) American National Standards Institute• NCRP – Report 86 (1986) National Council on Radiation Protection andMeasurements• ICNIRP (1996) International Commission on Non-Ionizing RadiationProtection;• DHWC – Safety Code 6 Department of Health and Welfare CanadaThose standards were developed by independent scientific organizations throughperiodic and thorough evaluation of scientific studies. The standards include asubstantial safety margin designed to assure the safety of all persons, regardless ofage and health. The exposure standard for wireless mobile phones employs a unit ofmeasurement known as the Specific Absorption Rate, or SAR. The SAR limit set bythe FCC is 1.6 W/kg1 . Tests for SAR are conducted using standard operatingpositions specified by the FCC with the phone transmitting at its highest certifiedpower level in all tested frequency bands. Although the SAR is determined at thehighest certified power level, the actual SAR level of the phone while operating canbe well below the maximum value. This is because the phone is designed to operate atmultiple power levels so as to use only the power required to reach the network. Ingeneral, the closer you are to a wireless base station antenna, the lower the poweroutput. Before a phone model is available for sale to the public, it must be tested andcertified to the FCC that it does not exceed the limit established by thegovernment-adopted requirement for safe exposure. The tests are performed inpositions and locations (for example, at the ear and worn on the body) as required bythe FCC for each model. While there may be differences between the SAR levels ofvarious phones and at various positions, they all meet the government requirement forsafe exposure. The FCC has granted an Equipment Authorization for this modelphone with all reported SAR levels evaluated as in compliance with the FCC RFemission guidelines. SAR information on this model phone is on file with the FCCand can be found under the Display Grant section of http://www.fcc.gov/oet/fccid1. 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 togive additional protection for the public and to account for any variations in measurements.
