Section 4A. Important Safety Information

171

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

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 Web
site at www.fcc.gov.
