USING YOUR HAND-HELD PORTABLE
CELLULAR TELEPHONE
First introduced in 1984, the hand-held portable cellular
telephone is one of the most exciting and innovative elec-
tronic products ever developed. With it you can stay in
contact with your office, your home, emergency services,
and others.
For the safe and efficient operation of your phone,
observe these guidelines.
Your cellular telephone is a radio transmitter and receiver.
When it is ON, it receives and also sends out radio fre-
quency (RF) energy. The phone operates in the frequency
range of 824 MHz to 894 MHz and employs commonly used
frequency modulation (FM) techniques. When you use your
phone, the cellular system handling your call controls the
power level at which your phone transmits. The power level
can range from 0.006 of a watt to 0.6 of a watt.
Exposure to Radio Frequency Energy
In 1991 the Institute of Electrical and Electronics Engineers
(IEEE), and in 1992 the American National Standards
Institute (ANSI) updated the 1982 ANSI Standard for safety
levels with respect to human exposure to RF energy. Over
120 scientists, engineers, and physicians from universities,
government health agencies, and industry, after reviewing
the available body of research, developed this updated
Standard. In March, 1993, the Federal Communications
Commission (FCC) proposed the adoption of this updated
Standard.
The design of your phone complies with this updated
Standard. Of course, if you want to limit RF exposure even
further than the updated ANSI Standard, you may choose
to control the duration of your calls and operate your phone
in the most power efficient manner.
Efficient Phone Operation
For your phone to operate at the lowest power level,
consistent with satisfactory call quality, please observe the
following guidelines:
