READ THIS INFORMATION BEFORE USING
YOUR MOBILE CELLULAR TELEPHONE
The cellular telephone is one of the most exciting and inno-
vative electronic products ever developed. With it you can
stay in contact with your office, your home, emergency ser-
vices, and others.
For the safe and efficient operation of your phone,
observe these guidelines.
Your mobile cellular telephone is a radio transmitter and re-
ceiver. When the phone is ON, the antenna is the part of the
phone that sends out and receives radio frequency (RF) en-
ergy. The phone operates in the frequency range of 824 MHZ
to 894 MHZ and employs commonly used frequency modu-
lation (FM) techniques. When you use your phone, the cel-
lular 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 3 watts.
EXPOSURE TO RADIO FREQUENCY ENERGY
In 1991 the Institute of Electrical and Electronics Engineers
(IEEE), and in 1992 the American National Standards Insti-
tute (ANSI) updated the 1982 ANSI Standard for safety lev-
els with respect to human exposure to RF energy. Over 120
scientists, engineers, and physicians from universities, gov-
ernment health agencies, and industry, after reviewing the
available body of research, developed this updated Standard.
In March, 1993, the U.S. Federal Communications Commis-
sion (FCC) proposed the adoption of this updated Standard.
To operate within this updated ANSI Standard, use your
phone as described under "Efficient Phone Operation."
EFFICIENT PHONE OPERATION
Do not operate your mobile cellular telephone when holding the
antenna, or when any person is within 4 inches (10 centimeters)
of the antenna.
A person or object within 4 inches (10 centimeters) of the an-
tenna could impair call quality, cause your phone to operate at a
