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 that are
rated have the rating on their box or a label located on the box.
The ratings are not guarantees. Results will vary depending on
the user's hearing device and hearing loss. If your hearing device
happens to be vulnerable to interference, you may not be able to
use a rated phone successfully. Trying out the phone with your
hearing device is the best way to evaluate this.
M-Ratings: Phones rated M3 or M4 meet FCC requirements and
are likely to generate less interference to hearing devices than
phones that are not labeled. M4 is the better/higher of the two
ratings.
T-Ratings: Phones rated T3 or T4 meet FCC requirements and
are likely to generate less interference to hearing devices than
