Some hearing devices are more immune than others to
this interference noise and phones also vary in the
amount of interference they generate. The wireless
telephone industry has developed a rating system for
wireless phones to assist hearing device users in finding
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.
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.)
