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- 2011).
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.
This phone has been tested and rated for use with hearing
aids for some of the wireless technologies that it uses.
