CHAPTER 5. Safety
▣
IMPORTANT
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 CDMA 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 0.00001 milli-Watt to 200 milli-
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.
Do not hold the antenna when the phone is “IN USE”. Holding the antenna affects call quality and may cause
the phone to operated at a higher power level than needed.
