108 4A. Important Safety Information

Charging

䢇In order to avoid damage, charge the battery only in temperatures that
range from 32° F to 113° F (0° C to 45° C).
䢇Don’t use the battery charger in direct sunlight or in high humidity areas,
such as the bathroom.
䢇The battery may need recharging if it has not been used for a long
period of time.
䢇It’s best to replace the battery when it no longer provides acceptable
performance. It can be recharged hundreds of times before it needs
replacing.

Storing

䢇Don’t store the battery in high temperature areas for long periods of
time. It’s best to follow these storage rules:
Less than one month:
-4° F to 140° F (-20° C to 60° C)
More than one month:
-4° F to 113° F (-20° C to 45° C)

Disposal of Lithium Ion (Li-Ion) Batteries

䢇Promptly dispose of used batteries in accordance with local regulations.
䢇Never dispose of the battery by incineration.
䢇Do not handle a damaged or leaking Li-Ion battery as you can be
burned.
䢇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 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 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 0.866 inches (2.2 centimeters) from your
body when transmitting. Use of non-approved accessories may violate
FCC RF exposure guidelines. Other accessories used with this device for
