Safety Guidelines

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 for immunity to this type of
interference. Your hearing device
manufacturer or hearing health
professional may help you find results
for your hearing device. The more
immune your hearing aid is, the less
likely you are to experience
interference noise from mobile
phones.
