HAC RATING
The FCC has created a rating system for cellular phones
regarding their HAC-related performance. This rating
helps consumers with hearing disabilities to nd phones
that work well with their hearing aid devices. The HAC
rating and measurement procedure are described in the
American National Standards Institute (ANSI C63.19-2011)
contains two rating standards: an “M” rating from 1 to
4 for hearing aids operating in microphone mode, and a
“T” rating from 1 to 4 for hearing aids operating in telecoil
mode. M-Rating stands for Microphone rating and indicates
the amount of reduction of RF interference between the
telephone and the hearing aid in acoustic coupling mode
(also called microphone mode). Phones rated M3 or M4
meet FCC requirements and generate less interference to
hearing devices set in microphone mode. T-Rating stands
for telecoil rating and represents inductive coupling with
hearing aids that are operating in telecoil mode. A tel coil
is a small piece of tightly wrapped wire, built into some
hearing aids. While the microphone of a hearing aid picks
up all sounds, the telecoil only picks up an electromagnetic
signal from the telephone. Thus, users of telecoil-equipped
hearing aids are able to communicate over the telephone
without the amplication of unwanted background noise.
Phones rated T3 or T4 meet FCC requirements and generate
less interference to hearing devices set in telecoil mode. A
combination of M-rating and T-rating denes the nal HAC
rating and is a deciding factor in selecting cellular phones
for people with hearing problems. A HAC compliant phone
could be rated:
• M3/T3
• M3/T4
• M4/T3
• M4/T4
Its resistance to interference. The best way to evaluate
the suitability of the phone is to try it with the intended
hearing aid device.
The model XP3800 have been tested for hearing aid
device compatibility and complies with the Federal
Communications Commission (FCC) requirements.
These devices are rated M3/T4.
