technologies that it uses. However, there may be some newer wireless technologies used
in this phone that have not been tested yet for use with hearing aids. It is important to
try the different features of this phone thoroughly and in different locations, using your
hearing aid or cochlear implant, to determine if you hear any interfering noise. Consult
your service provider or the manufacturer of this phone for information on hearing aid
compatibility. If you have questions about return or exchange policies, consult your
service
To determine the compatibility of a WD and a particular hearing aid, simply add the
numerical part of the hearing aid category (e.g. M2/T2=2) with the numerical part of the
WD emission rating (e.g., M3=3) to arrive at the system classification for this particular
combination of WD and hearing aid. A sum of 5 would indicate that the WD and hearing
aid would provide normal use, and a sum of 6 or greater would indicate that the WD and
hearing aid would provide excellent performance. A category sum of less than 4 would
likely result in a performance that is judged unacceptable by the hearing aid user.
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.
The tested M-Rating and T-Rating for this device (FCC ID: H8NTN502A1) are M3 and T3.
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
