Section 14: Health and Safety Information
221
Using Your Phone Near Other Electronic Devices
Section 14
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.
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.
