n
these storage rules:
Less than one month:
l
-4°F to 140°F (-20°C to 60°C)
More than one month:
l
-4°F to 113°F (-20°C to 45°C)
Disposal of Lithium Ion (Li-Ion) Batteries
Promptly dispose of used batteries in accordance with local regulations.
n
Never dispose of the battery by incineration.
n
Do not handle a damaged or leaking Li-Ion battery as you can be burned.

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).
