The wireless telephone industry has developed a rating
system for wireless phones, to assist hearing device users 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 be more usable with a hearing device's telecoil
("T Switch" or "Telephone Switch") than unrated phones. T4
is the better/higher of the two ratings. (Note that not all
hearing devices have telecoils in them.) Hearing devices may
also be measured.
Your phone meets the M3/T3 level rating. Hearing devices
may also be rated. Your hearing device manufacturer or
hearing health professional may help you find this rating.
This phone has been tested and rated for use with hearing
aids for some of the wireless 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
