Health and Safety Information       132

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.
