the rating of your hearing aid. Add the rating of your hearing aid and your
wireless device to determine probable usability:

ⅷ

Any combined rating equal to or greater than six offers best 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 wireless device, you will have a
combined rating of six for “best use.” This is synonymous for T ratings.

Sprint Nextel further suggests you experiment with multiple wireless 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 wireless device,
promptly return it to the store within 30 days of purchase. With the Sprint 30-day
Risk-Free Guarantee, you may return the wireless device within 30 days of
purchase for a full refund.

For more information, please consult the Safety and Product Information Guide
on the BlackBerry® User Tools CD that came with your device.
