Hearing Aid Compatibility 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.

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. 92 Export Law "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. "T" Rating: Phones rated T3 or T4 meet FCC requirements and are likely to be more usable with a hearing aid's telecoil ("T Switch" or "Telephone Switch") than unrated phones.

Ask your hearing health care professional for the rating of your hearing aid. Add the rating of your hearing aid and your phone to determine the estimated usability: • Any combined rating equal to or greater than six offers excellent use. • Any combined rating equal to five is considered normal use.

Hearing Aid Compatibility
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.
“T” Rating
: Phones rated T3 or T4 meet FCC requirements and are
likely to be more usable with a hearing aid's telecoil (“T Switch” or
“Telephone Switch”) than unrated phones. (T4 is the “better” or
higher of the two ratings.) On those models with a telecoil mode
setting, this rating is determined only with the phone so set. For
setting instructions, see “Features for the Hearing Impaired” in the
section entitled “Advanced Calling Features”. Note that not all
hearing aids have telecoils in them.
Hearing aids may also be measured for immunity to interference
from wireless phones and may have ratings similar to wireless
phones. Ask your hearing health care professional for the rating of
your hearing aid. Add the rating of your hearing aid and your phone
to determine the estimated usability:
•
Any combined rating equal to or greater than six offers
excellent use.
•
Any combined rating equal to five is considered normal
use.
