important to try the different features of your BlackBerry device thoroughly and in different
locations to determine if you hear any interfering noise when using this BlackBerry device with
your hearing aid or cochlear implant. Consult your wireless service provider about its return and
exchange policies and for information about hearing aid compatibility.
How the ratings work
M-Ratings: Wireless devices rated M3 or M4 meet FCC requirements and are likely to generate
less interference to hearing devices than wireless devices that are not labeled. M4 is the better
or higher of the two ratings.
T-Ratings: Wireless devices 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 wireless
devices. T4 is the better or higher of the two ratings. (Note that not all hearing devices have
telecoils in them.)
Hearing devices may also be measured for immunity to this type of interference. Your hearing
device manufacturer or hearing health professional may help you find results for your hearing
device. The more immune your hearing aid is, the less likely you are to experience interference
noise from wireless devices.

compatibility with wireless devices and other steps that the FCC has taken to ensure that
