Read This Information Before Using Your Hand-Held Portable Cellular Telephone
First introduction in 1984, the hand-held portable cellular telephone is one of the most exciting and
innovative electronic products ever developed.
With it you can stay in contact with your office, your home, emergency service, and others. For the
safe and efficient operation of your phone, observe these guidelines.
Your cellular phone is a radio transmitter and receiver. When it is ON, it receives and also sends out
radio frequency (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 calls controls the power level at which your phone transmits. The power
level can range from 0.006 of a watt to .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) updates 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 boy of research, developed this updated
Standard. In March, 1993, the US 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 opration 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:
If your phone has an extendable antenna, extend it fully. Some models allow you to place a call with
the antenna retracted. However, your phone operates more efficiently with the antenna fully extended.
Hold the phone as you would any other telephone. While speaking directly into the mouthpiece,
position the antenna up and over your shoulder.
