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)

Disposal of Lithium Ion (Li-Ion) Batteries
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.
Radiofrequency (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 watts to 0.2 watts in digital mode.
Knowing Radiofrequency 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
