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 for your phone is maintained,
secondary transmitters such as Bluetooth
and WLAN(this phone does not have
WLAN) components must be disabled
during a call. See page 79 for the
instructions to disable these components.
