Section 2A: Important Safety Information 55
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 (2.0 centimeters) from your
body when transmitting. Use of non- approved accessories
may violate FCC RF exposure guidelines.
For more information about RF exposure, visit the FCC Web
site at
