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
