Radio Frequency (RF)Energy

Understanding How YourPhone Operates

Yourphone is basically a radio transmitterand receiver. When it’s
turned on, it receives and transmits radio frequency (RF)signals.
When you use yourphone, the system handling yourcall
controls the powerlevel. This powercan range from 0.006 watt to
0.2 watt in digital mode.

Knowing Radio FrequencySafety

The design of yourphone 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 forsafety levels with
respect to human exposure to RFsignals. More than 120
scientists, engineers and physicians from universities,
government health agencies and industries developed this
updated standardafterreviewing the available body of research.
In 1993, the Federal Communications Commission (FCC)
adopted this updated standardin a regulation. In August 1996,
the FCC adopted hybrid standard consisting of the existing
ANSI/IEEEstandard and the guidelines published by the
National Council of Radiation Protection and Measurements
(NCRP).
