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

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.
