Section 4A. Important Safety Information 199
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.
To ensure that the Hearing Aid Compatibility rating for your
phone is maintained, secondary transmitters such as Bluetooth
and WLAN components must be disabled during a call. See
“Turning Bluetooth On and Off” on page 126 for instructions to
disable these components.
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. With the Sprint
30-day Risk-Free Guarantee, you may return the phone within
30 days of purchase for a full refund. More information about
hearing aid compatibility may be found at: www.fcc.gov,
www.fda.gov
, and www.accesswireless.org.
