the body. Use of other accessories may not ensure compliance
with FCC RF exposure guidelines. If you do not use a body-worn
accessory and are not holding the phone at the ear, position the
handset a minimum of 1.5 cm from your body when the phone is
switched on.
HEARING AID COMPATIBILITY HAC FOR
WIRELESS TELECOMMUNICATIONS DEVICES
THIS PHONE HAS A HAC RATING OF XX
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 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.
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
ratio.
