TELECOMMUNICATIONS DEVICES
PCD’S COMMITMENT
PCD believes that all of our customers should be able to enjoy the benefits of digital
wireless technologies. We are committed to providing a selection of compatible devices
for our customers who wear hearing aids.
THIS PHONE HAS A HAC RATING OF M3/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 telecoil 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 (telecoil 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.
