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
