compatibility with hearing aids. If the box for your
particular model has "Rated for Hearing Aids" printed
on it, the following explanation applies.
When some mobile 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
ratings for some of their mobile 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 on the box.

depending on the user's hearing device and hearing

to interference, you may not be able to use a rated
phone successfully. Trying out the phone with your

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 for immunity
to this type of interference. Your hearing device
