Some hearing devices are more immune than others to this
interference noise, and phones also vary in the amount of
interference noise they may generate. ANSI standard C63. 1 9
was developed to provide a standardized means of measuring
both wireless phone and hearing devices to determine usability
rating categories for both.
Ratings have been developed for mobile phones to assist
hearing device users find phones that may be compatible with
their hearing device. Not all phones have been rated for
compatibility with hearing devices. Phones that have been
rated have a label located on the box.
.
M4 rating
These ratings are not guarantees. Results will vary depending
on the user's hearing device and individual type and degree of
hearing loss. If a hearing device is particularly vulnerable to
interference noise; even a phone with a higher rating may still
cause unacceptable noise levels in the hearing device. Trying
out the phone with your hearing device is the best way to
evaluate it for your personal needs.
: Phones rated M3 or M4 meet FCC requirements for
M-Ratings
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.)
: Phones rated T3 or T4 meet FCC requirements and
T-Ratings
are likely to be more usable with a hearing device's telecoil ("T
Switch"or "Telephone Switch") than unrated phones. (T4 is the
188
4A. Important Safety Information
Your SPH-M930 has an
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:
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.
