SAFETY AND WARRANTY
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 handsets under the Hearing Aid Compatibility Act of 1988
(HAC Act) to require digital wireless handsets 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 handsets 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 handsets also vary in the
amount of interference they generate.
The wireless device industry has developed a rating system for
wireless handsets, to assist hearing device users find handsets that
may be compatible with their hearing devices. Not all handsets have
been rated. Handsets 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 handset successfully. Trying out the handset with your
hearing device is the best way to evaluate it for your personal needs.
Your mobile device model complies with FCC rules governing hearing
aid compatibility. These rules require an M4 microphone or higher
value. The M-value, shown on the device box, refers to lower radio
frequency (RF) emissions. A higher M-value generally indicates that a
device model has a lower RF emissions level, which may improve the
likelihood that the device will operate with certain hearing aids.
Some hearing aids are more immune than others are to interference.
Please consult your hearing health professional to determine the
M-rating of your hearing aid and whether your hearing aid will work
with this device.
