166 Section 4A: ImportantSafety Information

Using Your Phone With a Hearing AidDevice
Your phone has been tested for hearing aid device compatibility. When some
wireless phones are used near some hearing devices (hearing aids and
cochlear implants), users may detecta buzzing, humming, or whining noise.
Some hearing devices are more immune than others to this interference
noise, and phones also vary in the amountof interference they generate.
The wireless telephone industry has developed ratings for some of their
mobile phones, to assisthearing device users in finding phones thatmay be
compatible with their hearing devices. Notall phones have been rated.
Phones thatare rated will have the rating on the box. Your Fusic™ has an
M3 rating.
Note: Phones rated M3 or M4 meetFCC requirements and may generate less
interference to hearing devices than phones thatare notlabeled. M4 is the
better/higher of the two ratings.
The M3/M4 ratings do notguarantee successful interoperation between
your phone and hearing aid device. Results will vary depending on the level
of immunity of your hearing device and degree of your hearing loss.
The more immune your hearing aid device is, the less likely you are to
experience interference noise from your wireless phone. Hearing aid
devices should have ratings similar to phones. Ask your hearing healthcare
professional for the rating of your aids. Mostnew hearing aids have atleast
an M2 immunity level. Add the “M”ratings of your hearing aid and your
phone to determine probable usability:
Any combined rating equal to or greater than six offers bestuse.
Any combined rating equal to five is considered normal use.
Any combined rating equal to four is considred usable.
Thus, if you pair an M3 hearing aid with an M3 phone, you will have a
combined rating of six for “bestuse.”
Sprintfurther suggests you experimentwith multiple phones (even those
notlabeled M3 or M4) while in the store to find the one thatworks best with
your hearing aid device. Should you experience interference after
purchasing your phone, promptly return itto the store. With the Sprint
14 Day Risk Free Guarantee you may return the phone within 14 days of
purchase for a full refund.
