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
