Safety Guidelines

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.

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 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 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.
