Virgin LS620 User Manual page 168

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.
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.
