FCC Hearing-Aid Compatibility (HAC)
Regulations for Wireless Devices
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 enter that the Hearing Aid Compatibility
rating 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 154 for instructions to
disable these components.
