Safety 113 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.

the two ratings.
T-Ratings: Phones rated T3 or T4 meet

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

The M mark is intended to be

are referenced in Section 20.19 of the

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.
