Common Causes of Battery Drain

● Playing games or using the Web.
● Keeping backlighting on.
● Operating the phone far away from a

base station or cell site.

● Using data cables or accessories.
● Operating the phone when no service is

available, or service is available
intermittently.

● High volume settings.
● Repeating sound, vibration, or lighted

alerts.

Disposal of Lithium Ion (Li-Ion)
Batteries

● Promptly dispose of used batteries in

accordance with local regulations.

● Never dispose of the battery by

incineration.

● 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
authorized service center.

Special Note: Be sure to dispose of

your battery properly. In some areas,
the disposal of batteries in household or

Radio Frequency (RF)
Energy

Understanding How Your Phone
Operates

Your phone is a radio transmitter and
receiver. When it’s turned on, it receives
and transmits radio frequency (RF) signals.
Your phone is designed to transmit just
enough RF power to reach the network.
The system handling your call controls the
RF power level. Depending on network
conditions, your phone may operate at an
actual SAR level below the maximum value
specified. Your phone is designed not to
exceed the recommended international
guidelines for limits on RF exposure.

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
