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

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. 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.
In order to avoid damage, charge the battery only in 
temperatures that range from 32° F to 113° F (0° C to 45° C).
Don’t use the battery charger in direct sunlight or in high 
humidity areas, such as the bathroom.
Never dispose of the battery by incineration.
Keep the metal contacts on top of the battery clean.
Don’t attempt to disassemble or short-circuit the battery.
