Huawei M835 Quick Start - Manual (Page 20)

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.
Your phone meets the M4/T3 level rating. Hearing devices may also be rated. Your
hearing device manufacturer or hearing health professional may help you find this
rating.
