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 find 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.
M-Ratings: Phones rated M3 or M4 meet FCC requirements and
are likely to generate less interference to hearing devices than
phones that are not labeled. M4 is the better/higher of the two
ratings.
