• M-Ratings : Phones rated M3 or M4 meet FCC requirements and are likely to generate less interference to hearing devices than mobile devices 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 work better with a hearing device’s telecoil (“T Switch” or “Telephone Switch”) than unrated phones. T4 is the better/ higher of the two ratings. (Note not all hearing devices have telecoils in them.) The tested M-Rating and T-Rating for this device ( FCC ID: 2A9QD-NX769J ) are M3 and T3.
