Hearing Aid Compatibility (HAC) for Wireless Telecommunication
Devices
This phone has a HAC rating 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 Amer-
ican 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 .
