HAC 17
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- 2007). 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 is the best way to evaluate it for your
personal needs.
This phone has been tested and rated for use with hearing aids for some of the wireless technologies that it
uses. However, there may be some newer wireless technologies used in this phone that have not been
tested yet for use with hearing aids. It is important to try the different features of this phone thoroughly
and in different locations, using your hearing aid or cochlear implant, to determine if you hear any
interfering noise. Consult your service provider or the manufacturer of this phone for information on
hearing aid compatibility. If you have questions about return or exchange policies, consult your service
provider or phone retailer.
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.)
Your phone meets the M3/T3 level rating.
Hearing devices may also be rated. Your hearing device manufacturer or hearing health professional may
help you find this rating. For more information about FCC Hearing Aid Compatibility, please go to
