The wireless telephone industry has
developed a rating system for wireless
phones, to assist hearing device users
to find phones that may be compatible
with their hearing devices. Not all
phones have been rated. Phones that
are rated have the rating on their box or
a label located on the box.
The ratings are not guarantees. Results
will vary depending on the user's
hearing device and hearing loss. If your
hearing device happens to be vulnerable
to interference, you may not be able to
use a rated phone successfully. Trying
out the phone with your hearing device
is the best way to evaluate it for your
personal needs.
M-Ratings: Phones rated M3 or M4
meet FCC requirements and are likely
to generate less interference to hearing
devices than phones that are not
labeled. M4 is the better/higher of the
two ratings.
T-Ratings: Phones rated T3 or T4 meet
FCC requirements and are likely to
generate less interference to hearing
devices than phones that are not
