Important Safety Information

M-Ratings
: Phones rated M3 or M4 meet FCC
requirements for hearing aid compatibility and are
likely to generate less interference to hearing devices
than unrated phones. (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.)
Note:
This phone has been tested and rated for use
with hearing aids for some of the wireless
technologies that it uses. However, there may be
some newer wireless technologies used in this
phone that have not been tested yet for use
with hearing aids. It is important to try the
different features of this phone thoroughly
and in different locations, using your hearing
aid or cochlear implant, to determine if you
hear any interfering noise. Consult your
service provider or the manufacturer of this
phone for information on hearing aid
compatibility. If you have questions about
return or exchange policies, consult your
service provider or phone retailer.
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:
Ɣ
Any combined rating equal to or greater than six
offers excellent use.
Ɣ
Any combined rating equal to five is considered
normal use.
Ɣ
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.
