FOR YOUR SAFETY
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 M4/T3 level rating.
Hearing devices may also be rated. Your hearing device 
manufacturer or hearing health professional may help you 
nd this rating. For more information about FCC Hearing Aid
