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. 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 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. Because the
phone is designed to operate at multiple power levels 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 (e.g., at the ear and worn on the 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 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 after searching on FCC ID
ZNFLS777
Additional information on Specific Absorption Rates (SAR) can be found on the Cellular
Telecommunications Industry Association (CTIA) website at http://www.ctia.org/.
* 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.
FCC Hearing-Aid Compatibility (HAC) Regulations for
Wireless Devices
On July 10, 2003, the U.S. Federal Communications Commission (FCC) Report and Order in WT Docket
01-309 modified the exception of wireless phones under the Hearing Aid Compatibility Act of 1988 (HAC
Act) to require digital wireless phones be compatible with hearing-aids. The intent of the HAC Act is to
ensure reasonable access to telecommunications services for persons with hearing disabilities. While
some wireless phones are used near some hearing devices (hearing aids and cochlear implants), users
may detect a buzzing, humming, or whining noise. Some hearing devices are more immune than others
to this interference noise, and phones also vary in the amount of interference they generate. The wireless
telephone industry has developed a rating system for wireless phones, to assist hearing device users to
find phones that may be compatible with their hearing devices. Not all phones have been rated. Phones
