usability:
ⅷ
Any combined rating equal to or greater than six offers
excellent use.

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.
It is further suggested 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 where purchased for exchange or refund. More
information about hearing aid compatibility may be found at: www.fcc.gov

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. The
manufacturer is not aware of similar problems with manufacturer phones
resulting from the proper use of batteries and accessories approved by
the manufacturer of your phone. Use only manufacturer-approved
batteries and accessories found through your phone’s manufacturer.
Buying the right batteries and accessories is the best way to ensure
they’re genuine and safe.
ⅷ
Do not disassemble or open crush, bend or deform, puncture or shred the
battery.
