out the device with your hearing device is the best way to
evaluate it for your personal needs.
M-Ratings: Devices rated M3 or M4 meet FCC requirements
for hearing aid compatibility and are likely to generate less
interference to hearing devices than unrated devices. (M4 is the
better/higher of the two ratings.)
T-Ratings: Devices 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 devices. (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 devices and should have
ratings similar to devices. Ask your hearing healthcare
professional for the rating of your hearing aid. Add the rating of
your hearing aid and your device 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 device, you will
have a combined rating of six for “excellent use.” This is
synonymous for T ratings.
Sprint further suggests you experiment with multiple devices
(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 device, promptly
return it to the store within 30 days of purchase. With the Sprint
30-day Risk-Free Guarantee, you may return the device 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.
Getting the Best Hearing Device
Experience With Your Device
To further minimize interference:
ⅷ Set the device’s display and dial pad backlight settings to
ensure the minimum time interval:
1. Press and touch Main ( ) > Settings > Display >
Brightness, Backlight Dim, or Brightness Off .
2. Touch the minimum time interval setting. (Brightness is
adjustable by moving the slider either left or right.)
ⅷ Position the device so the internal antenna is farthest from
your hearing aid.
ⅷ Move the device around to find the point with least
interference.
