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 C63.19
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.
Your SPH-M910 has an
M4 and T3 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.
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.)
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:
ⅷ Any combined rating equal to or greater than six offers
excellent use.
ⅷ Any combined rating equal to five is considered normal use.
ⅷ 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.
Sprint further suggests you experiment with multiple phones
(even those not labeled M3/T3 or M4/T4) while in the store to
find the one that works best with your hearing aid device.
Should you experience interference or find the quality of
service unsatisfactory after purchasing your phone, promptly
return it to the store within 30 days of purchase. (A restocking
Note: New Technologies, Including Wi-Fi
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 newer wireless technologies (including Wi-Fi)
used in this phone that have not been tested for use with
hearing aids.
