HEARING AID COMPATIBILITY (HAC) REGULATIONS
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,
