minimum rating of "M3" for RF emissions under the
ANSI C63.19 standard. The "M" rating refers to the
phone's RF emissions level for use with hearing
aids operating in the microphone setting.
The higher the phone's "M" rating, the more likely
the phone is compatible with a hearing aid
operating in the microphone setting. Hearing aids
also have ratings similar to wireless phones.
Most newer hearing aid models receive at least
an M2 rating.
To determine the level of compatibility between
your hearing aid and this Assurance Wireless HAC
certified phone, combine the M rating of your
hearing aid and the M rating of this phone. For
example, if you pair an M3 hearing aid with an M4
phone, you will achieve a combined rating of 7.
• Any combined rating equal to or greater than
6 provides excellent performance.
• Any combined rating equal to 5 offers
good performance.
• Any combined rating equal to 4 offers
acceptable performance.
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 choose the proper rating for your
mobile phone. The more immune your hearing aid
is, the less likely you are to experience interference
noise from mobile phones.
