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.
