Hearing aid devices may also be measured for immunity to
interference noise from wireless phones and should have
ratings similar to phones. Ask your hearing healthcare
professional for the rating of your hearing aid. Add the
rating of your hearing aid and your phone to determine
probable usability:
•
Any combined rating equal to or greater than six offers
excellent use.
•
Any combined rating equal to five is considered normal
use.
•
Any combined rating equal to four is considered usable.
Thus, if you pair an M3 hearing aid with an M3 phone, you
will have a combined rating of six for "excellent use." This is
synonymous for T ratings.

wireless phone batteries overheating, catching fire, or
exploding. It appears that many, if not all, of these reports
involve counterfeit or inexpensive, aftermarket-brand
batteries with unknown or questionable manufacturing
standards. Use only manufacturer-approved batteries
