Hearing Aid Compatibility with Mobile Phones
Some Motorola phones are measured for compatibility with

hearing aids. If the box for your particular model has "Rated for
Hearing Aids" printed on it, the following explanation applies.
When some mobile 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 ratings for some of
their mobile 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 on the box.

1. In the United States and Canada, the SAR limit for mobile phones used
by the public is 1.6 watts/kg (W/kg) averaged over one gram of tissue.
The standard incorporates a substantial margin of safety to give
additional protection for the public and to account for any variations in
measurements.
2. The SAR information includes the Motorola testing protocol,
assessment procedure, and measurement uncertainty range for this
product.
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.
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
