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 watts to 0.2 watts 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 Telecom 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-Telecom approved
accessories may violate FCC RF exposure guidelines.

Specific Absorption Rate (SAR) for mobile
phones
The SAR is a value that corresponds to the relative
amount of RF energy absorbed in the head of a user
of a wireless handset.
The SAR value of a phone is the result of an extensive
testing, measuring and calculation process. It does
not represent how much RF the phone emits. All
phone models are tested at their highest value in
strict laboratory settings. But when in operation, the
