Hearing Aid Compatibility (HAC)
regulations for Mobile phones
In 2003, the FCC adopted rules to
make digital wireless telephones
compatible with hearing aids and
cochlear implants. Although analog
wireless phones do not usually
cause interference with hearing
aids or cochlear implants, digital
wireless phones sometimes do
because of electromagnetic energy
emitted by the phone's antenna,
backlight, or other components.
Your phone is compliant with FCC
HAC regulations (ANSI C63.19).
While some wireless phones are
used near some hearing devices
(hearing aids and cochlear implants),
users may detect a buzzing,
humming, or whining noise.
Some hearing devices are more
immune than others to this
interference noise and phones also
vary in the amount of interference
they generate.
The wireless telephone industry
has developed a rating system for
wireless phones to assist hearing
device users in finding phones that
may be compatible with their
hearing devices. Not all phones
have been rated. Phones that are
rated have the rating on their box or
a label located on the box. The
ratings are not guarantees. Results
will vary depending on the user's
hearing device and hearing loss. If
your hearing device happens to be
vulnerable to interference, you may
not be able to use a rated phone
successfully. Trying out the phone
with your hearing device is the best
way to evaluate it for your personal
needs.
