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. However, there may be some newer wireless
technologies used in this phone that have not been tested
yet for use with hearing aids. It is important to try the
different features of this phone thoroughly and in different
locations, using your hearing aid or cochlear implant, to
determine if you hear any interfering noise. Consult your
service provider or the manufacturer of this phone for
