Health and Safety Information 48
Mobile devices that are rated have the
rating on their box or a label located on
the box.
The ratings are not guarantees. Results
will vary depending on the user's hearing
device and hearing loss. If your hearing
device happens to be vulnerable to
interference, you may not be able to use
a rated mobile device successfully.
Trying out the mobile device with your
hearing device is the best way to
evaluate it for your personal needs.
M-Ratings: Wireless mobile devices 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. M-ratings refer to
enabling acoustic coupling with hearing
aids that do not operate in telecoil mode.
T-Ratings: Mobile devices rated T3 or T4
meet FCC requirements and are likely to
generate less interference to hearing
devices than mobile devices that are not
labeled. T4 is the better/higher of the
two ratings. T-ratings refer to enabling
inductive coupling with hearing aids
operating in telecoil mode.
