LG H910, User Manual

Page: 149 / 175

For Your Safety 148
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 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.
