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.
You M328 is compliant with FCC Hearing Aid Compatibility (HAC) regulations.
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 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 interference to hearing devices than phones that are not labeled.
M4 is the better/higher of the two ratings.M328 support M3.
Hearing devices may also be rated. Your hearing device manufacturer or hearing
health professional may help you find this rating.
