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: Ⅲ Less than one month: -4° F to 140° F (-20° C to 60° C) Ⅲ 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. For safe disposal options of your Li-Ion batteries, contact your nearest Sprint authorized service center. Special Note: Be sure to dispose of your battery properly. In some areas, the disposal of batteries in household or business trash may be prohibited. Radio Frequency (RF) Energy Understanding How Your Phone Operates Your phone is basically a radio transmitter and receiver. When it's turned on, it receives and transmits radio frequency (RF) signals. When you use your phone, the system handling your call controls the power level. This power can range from 0.006 watt to 0.2 watt in digital mode. Knowing Radio Frequency Safety The design of your phone complies with updated NCRP standards described below. In 1991-92, the Institute of Electrical and Electronics Engineers (IEEE) and the American National Standards Institute (ANSI) joined in updating ANSI's 1982 standard for safety levels with respect to human exposure to RF signals. More than 120 scientists, engineers and physicians from universities, government health agencies and industries developed this updated standard after reviewing the available body of research. In 1993, the Federal Communications Commission (FCC) adopted this updated standard in a regulation. In August 1996, the FCC adopted hybrid standard consisting of the existing ANSI/IEEE standard and the guidelines published by the National Council of Radiation Protection and Measurements (NCRP). Body-Worn Operation To maintain compliance with FCC RF exposure guidelines, if you wear a handset on your body, use a Sprint-supplied or Sprint-approved carrying case, holster or other body-worn accessory. If you do not use a body-worn accessory, ensure the antenna is at least 7/16 inch (1.5 centimeters) from your body when transmitting. Use of non-Sprint-approved accessories may violate FCC RF exposure guidelines. For more information about RF exposure, visit the FCC website at www.fcc.gov. Important Safety Information 4A.
