LG 210 - Manual (Page 92)

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 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.
