Fcc Hearing-Aid Compatibility - LG VX8350 User Manual

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.
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 59 for instructions to
disable these components.
