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 about its return and exchange policies and for information on hearing aid compatibility. 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 device 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 devices resulting from the proper use of batteries and accessories approved by Sprint or the manufacturer of your device. Use only Sprint-approved or Samsung-approved batteries and accessories found at Sprint Stores or through Samsung, 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. ⅷ The battery may need recharging if it has not been used for a long period of time. ⅷ It's best to replace the battery when it no longer provides acceptable performance. It can be recharged hundreds of times before it needs replacing. ⅷ Don't store the battery in high temperature areas for long periods of time. It's best to follow these storage rules: Less than one month: -4° F to 140° F (-20° C to 60° C) More than one month: -4° F to 113° F (-20° C to 45° C) Disposal of Lithium Ion (Li-Ion) Batteries Do not handle a damaged or leaking Li-Ion battery as you can be burned.
