HEARING AID COMPATIBILITY HAC FOR WIRELESS TELECOMMUNICATIONS
DEVICES
THIS PHONE HAS A HAC RATING OF M4/T3
WHAT IS HEARING AID COMPATIBILITY?
The Federal Communications Commission has implemented rules and
a rating system designed to enable people who wear hearing aids to
more effectively use these wireless telecommunications devices. The
standard for compatibility of digital wireless phones with hearing aids
is set forth in American National Standard Institute (ANSI) standard
C63.19. There are two sets of ANSI standards with ratings from one to
four (four being the best rating): an "M" rating for reduced
interference making it easier to hear conversations on the phone
when using the hearing aid microphone, and a "T" rating that enables
the phone to be used with hearing aids operating in the tele-coil
mode thus reducing unwanted background noise.
HOW WILL I KNOW WHICH WIRELESS PHONES ARE HEARING AID
COMPATIBLE?
The Hearing Aid Compatibility rating is displayed on the wireless phone
box.
A phone is considered Hearing Aid Compatible for acoustic coupling
(microphone mode) if it has an "M3" or "M4" rating. A digital wireless
phone is considered Hearing Aid Compatible for inductive coupling
(tele-coil mode) if it has a "T3" or "T4" rating.
HOW WILL I KNOW IF MY HEARING AID WILL WORK WITH A PARTICULAR
DIGITAL WIRELESS PHONE?
You'll want to try a number of wireless phones so that you can decide
which works the best with your hearing aids. You may also want to talk
with your hearing aid professional about the extent to which your hearing
aids are immune to interference, if they have wireless phone shielding,
and whether your hearing aid has a HAC rating.
FCC Hearing-Ai d Compatibility (HAC)
The (MXG-408) has been tested for hearing aid compatibility. This
device has an M4 and T3 rating. When some wireless devices are
used near some hearing devices such as hearing aids and implants,
users may detect a buzzing or humming noise. Some hearing devices
