Hearing Aid Compatibility (HAC) for Wireless Telecommunication Devices
This phone has a HAC rating of M3/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 use these wireless telecommunications devices more effectively. 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.
