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 electromag-
netic energy emitted by the phone’s 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 fi nd 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.
M-Ratings: Phones rated M3 or M4 meet FCC requirements and are likely to generate less inter-
ference 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 bet-
ter/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 fi nd this rating.
This phone has been tested and rated for use with hearing aids for some of the wireless technol-
