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 PK76300 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 PK76300 is rated T4.
Please power off the Bluetooth function while using hearing aid devices with your
PK76300.
Hearing devices may also be rated. Your hearing device
manufacturer or hearing health professional may help you
find this rating. Higher ratings mean that the hearing device is
relatively immune to interference noise.
