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.
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 better/higher of the two ratings. (Note that not all hearing 
devices have telecoils in them.)
Hearing devices may also be measured for immunity to this type of interference. 
Your hearing device manufacturer or hearing health professional may help you find 
results for your hearing device. The more immune your hearing aid is, the less likely 
you are to experience interference noise from mobile phones.

WHO Information
Present scientific information does not indicate the need for any special precautions 
for the use of mobile phones. If you are concerned, you may want to limit your own 
or your children’s RF exposure by limiting the length of calls or by using handsfree 
devices to keep mobile phones away from your head and body.
