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 find 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 example to
the left, 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
defined as a signal quality that's
acceptable for normal operation.
The M mark is intended to be
synonymous with the U mark. The T
mark is intended to be synonymous
with the UT mark. The M and T
marks are recommended by the
Alliance for Telecommunications
Industries Solutions (ATIS). The U
and UT marks are referenced in
Section 20.19 of the FCC Rules. The
HAC rating and measurement
procedure are described in the
American National Standards
Institute (ANSI) C63.19 standard.
When you're talking on a cell phone,
it's recommended that you turn the
BT (Bluetooth) mode off for HAC.
According to HAC policy(KDB
285076), we state this handset has
not been rated for hearing aid
compatibility with respect to the
WiFi capability.
