Hearing Aid Compatibility (HAC)
regulations for Mobile Phones
In 2003, the FCC adopted rules to make digital wireless

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

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
