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 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 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.
Use of non-approved accessories may violate FCC RF exposure guidelines.
For more information about RF exposure, visit the FCC Web site at www.fcc.gov .
Specific Absorption Rates (SAR) for Wireless 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 SAR of a phone
can be substantially less than the level reported to the FCC. This is because of a variety of
factors including its proximity to a base station antenna, phone design and other factors.
What is important to remember is that each phone meets strict federal guidelines.
Variations in SARs do not represent a variation in safety.
All phones must meet the federal standard, which incorporates a substantial margin of
safety. As stated above, variations in SAR values between different model phones do not
mean variations in safety. SAR values at or below the federal standard of 1.6 W/kg are
considered safe for use by the public.
The highest reported SAR values of the a920 are:
