Hearing Aid Compatibility

HAC
A number of Motorola phones have been tested for hearing
aid compatibility. When some wireless phones are used with
certain hearing aids, users may detect a noise which can
interfere with the effectiveness of the hearing aid.
Some hearing aids are more "immune" than others to this
interference noise, and phones can also vary in the amount of
interference noise they may generate. ANSI standard C63.19
was developed to provide a standardized means of
measuring both mobile phone and hearing aids to determine
usability rating categories for both.
Ratings have been developed for mobile phones to assist
hearing aid users find phones that may be compatible with
their hearing aid. Not all phones have been rated for
compatibility with hearing aids. Phones that have been rated
have a label with the rating(s) located on the box, and at
www.motorola.com/accessibility.
These ratings are not guarantees of compatibility. Results will
vary depending on the user's hearing aid and individual type
and degree of hearing loss. If a hearing aid is particularly
vulnerable to interference, even a phone with a higher rating
may still cause unacceptable noise levels in the hearing aid
Trying out the phone with your hearing aid is the best way to
evaluate it for your personal needs.
"M" Rating: Phones rated M3 or M4 meet FCC requirements
for hearing aid compatibility and are likely to generate less
interference to hearing aids than unrated phones. (M4 is the
"better" or higher of the two ratings.) On those models with
an extendable antenna, this rating is determined only with
the antenna extended.
