Radiofrequency (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 radiofrequency (RF) signals. When you use
your phone, the system handling your call controls the power level. This
power can range from 0.006 watts to 0.2 watts in digital mode.
Knowing Radiofrequency 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 7/16 inch (1.5 centimeters) from your body
when transmitting. Use of non- approved accessories may violate FCC RF
exposure guidelines.
