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 the Sprint supplied or approved carrying case,
holster or other body-worn accessory. If you do not use a body-worn
accessory, ensure the antenna is at least 2.2 centimeters from your body
when transmitting. Use of non-Sprint-approved accessories may violate
FCC RF exposure guidelines.
