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.

S

Hearing devices may also be

a f e

rated. Your hearing device

ty

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.
