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 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 it for your personal
needs.
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 rated. M4 is
the better/higher of the two ratings. Your PG06100 is
rated M4.
T-Ratings: Phones rated T3 or T4 meet FCC
requirements and are likely to be more usable with a
hearing aid’s telecoil than phones that are not rated. T4
is the better/higher of the two ratings. Your PG06100 is
rated T3.
