Telecommunications Devices
PCD’s Commitment

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 HAC RATINGS OF M4/T4
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.
