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
Compatibility, please go to http://www.fcc.gov/cgb/dro.
