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
M3

T4 level rating.
Hearing devices may also be rated. Your hearing
device manufacturer or hearing health
professional may help you find this rating. For
