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 phone successfully.
Trying out the phone with your hearing device is the best way to evaluate
it for your personal needs.
M-Ratings: Phones rated M3 or M4 meet FCC requirements and are
likely to generate less interference to hearing devices than phones 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 generate less interference to hearing devices than phones that are not
labeled. T4 is the better/higher of the two ratings.
Hearing devices may also be rated. Your hearing device manufacturer
or hearing health professional may help you fi nd this rating. Higher
ratings mean that the hearing device is relatively immune to interference
noise. The hearing aid and wireless phone rating values are then added
together. A sum of 5 is considered acceptable for normal use.
A sum of 6 is considered for best use.
In the above example, if a hearing aid meets the M2 level rating and
the wireless phone meets the M3 level rating, the sum of the two values
equal M5. This should provide the hearing aid user with “normal usage”
while using their hearing aid with the particular wireless phone. “Normal
usage” in this context is defi ned as a signal quality that’s acceptable for
normal operation.
