Hearing Aid Compatibility (HAC) regulations for Mobile phonesIn 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 phones antenna, 
backlight, or other components.
Your phone is compliant with FCC HAC regulations (ANSI C63.19).
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 find 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 users 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 is the best way to evaluate 
it for your personal needs.
M-Ratings: Phones rated M3 or M4 meet FCC requirements and are likely to 
generate less interference to hearing devices than phones that are not labeled.
M4 is the better/higher of the two ratings.
T-Ratings: Phones rated T3 or T4 meet FCC requirements and are likely to be more 
usable with a hearing device’s telecoil (“T Switch” or “Telephone Switch”) than unrated 
phones. T4 is the better/higher of the two ratings. (Note that not all hearing devices 
have telecoils in them.) Hearing devices may also be measured.
Your phone meets the M4/T3 level rating. Hearing devices may also be rated. Your 
hearing device manufacturer or hearing health professional may help you find this 
rating.
