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.
