Radio Frequency (Rf) Energy - LG LS740 User Manual

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
This device was tested for typical use with the back of the phone kept 0.39 inches (1.0 cm) from
the body. To comply with FCC RF exposure requirements, a minimum separation distance of
0.39 inches (1.0 cm) must be maintained between the user's body and the back of the phone,
including the antenna, whether extended or retracted. Third-party belt-clips, holsters, and similar
accessories containing metallic components may not be used. Avoid the use of accessories
that cannot maintain 0.39 inches (1.0 cm) distance between the user's body and the back of the
phone and have not been tested for typical body worn operations may not comply with FCC RF
exposure limits and should be avoided

If you are concerned about RF exposure, you can take a few simple steps to minimize your
exposure.
● Reduce the amount of time spent using your cell phone.
● Use speaker mode or a headset to place more distance between your head and the cell
phone.
Specific Absorption Rates (SAR) for Wireless Phones
The SAR value corresponds to the relative amount of RF energy absorbed into the head of a
user of a wireless handset.
