M-Ratings: Phones rated M3 or M4 meet
FCC requirements and are likely to gener-
ate less interference to hearing devices than
phones that are not labeled. M4 is the bet-
ter/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.)
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 more information about FCC
