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.
