battery pack to find the number. Once you have the FCC ID number for
a particular phone, follow the instructions on the website and it should
provide values for typical or maximum SAR for a particular phone.
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.

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 that are rated have the rating on their box or a label located on
