While some wireless phones are used near some hearing devices
(hearing aids and cochlear implants), users may detect a buzzing,
humming, or whining noise. 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. These ratings are not guaranteed. Results
will vary, depending on the level of immunity of your hearing
device and the degree of your 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
