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.
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 interfering noise. Consult your service provider or the
manufacturer of this phone for information on hearing aid compatibility.
If you have questions about return or exchange policies, consult your
service provider or phone retailer.
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.)
Your phone meets the M4/T4 level rating.
Hearing devices may also be rated. Your hearing device manufacturer
or hearing health professional may help you find this rating. For more
