186 4A. Important Safety
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.
Sprint further suggests 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 within 30 days of purchase. (A restocking
fee may be applied to exchanges. Visit
www.sprint.com/returns
for details.) 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 Phone
To further minimize interference:
ⅷ Set the phone’s display and keypad backlight settings to
ensure the minimum time intervals.
1. Press and touch Settings > Display > Brightness ,
or Dim .
2. Touch the minimum time interval setting.
ⅷ Position the phone so the internal antenna is farthest from
your hearing aid.
ⅷ 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.
ⅷ 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. Sprint is
not aware of similar problems with Sprint phones resulting
from the proper use of batteries and accessories approved
by Sprint or the manufacturer of your phone. Use only Sprint-
approved or manufacturer-approved batteries and
accessories found at Sprint Stores or through your phone’s
manufacturer, or call 1-866-866-7509 to order. They’re also
available at
www.sprint.com — click Accessories . Buying the
right batteries and accessories is the best way to ensure
they’re genuine and safe.
ⅷ In order to avoid damage, charge the battery only in
temperatures that range from 32° F to 113° F (0° C to 45° C).
ⅷ Don’t use the battery charger in direct sunlight or in high
humidity areas, such as the bathroom.
ⅷ Never dispose of the battery by incineration.
ⅷ Keep the metal contacts on top of the battery clean.
ⅷ Don’t attempt to disassemble or short-circuit the battery.
