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.
Phones rated M3/T3 or M4/T4 meet FCC requirements

and are likely to generate less interference to hearing

devices than phones that are not labeled. M4/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 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 is synonymous

for T ratings. 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 is 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.
To ensure that the Hearing Aid Compatibility rating for

your phone is maintained, secondary transmitters such as

Bluetooth and WLAN components must be disabled during a

call. See page 74 for instructions to disable these components.
