54 Important Safety Information
of the wireless technologies that it uses.
However, there may be some newer
wireless technologies used in this phone
that have not been tested yet for use with
hearing aids. It is important to try the
different features of this phone
thoroughly and in different locations,
using your hearing aid or cochlear
implant, to determine if you hear any
interfering noise. Consult your service
provider or the manufacturer of this
phone for information on hearing aid
compatibility. If you have questions about
return or exchange policies, consult your
service provider or phone retailer.
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:
Any combined rating equal to or greater
than six offers excellent use.
Any combined rating equal to five is
considered normal use.
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.
More information about hearing aid
compatibility may be found at:
www.fcc.gov, www.fda.gov, and

Getting the Best Hearing Device
Experience With Your Phone
To further minimize interference, move the
phone around to find the point with least
interference.
Caring for the Battery
Protecting Your Battery
The guidelines listed below help you get
the most out of your battery’s performance.
Recently there have been some public
reports of wireless phone batteries
overheating, catching fire, or exploding.
It appears that many, if not all, of these
reports involve counterfeit or
inexpensive, aftermarket-brand
batteries with unknown or questionable
manufacturing standards. Use only
manufacturer-approved batteries and
accessories. Buying the right batteries
and accessories is the best way to
ensure they’re genuine and safe.
Do not disassemble or open, crush,
bend or deform, or puncture or shred
the battery.
Do not modify or remanufacture,
attempt to insert foreign objects into the
battery, immerse or expose to water or
other liquids, expose to fire, explosion,
or other hazard.
