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
10
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 an
approved carrying case, holster or other body-worn
accessory. If you do not use a body-worn accessory,
ensure the antennas are at least 0.39 inches (1.0
centimeter) from your body when transmitting. Use
of non-approved accessories may violate FCC RF
exposure guidelines. Other accessories used with this
phone for body-worn operations must not contain any
