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 XX for instructions 
to disable these components.
