Safety Precautions
For safe and efficient operation of the phone, observe
the following guidelines.
The cellular telephone is a radio transmitter and receiver.
When the unit is powered on, the phone receives and sends
radio frequency (RF) energy. The phone operates in the cel-
lular frequency range of 824 MHz to 894 MHz and the per-
sonal communication system (PCS) range of 1850 MHz to
1990 MHz, and employs commonly used frequency modu-
lation (FM) techniques. When the phone is in use, the cellu-
lar system handling the call controls the power level at
which the phone transmits. The power level can range from
0.006 watt to 0.6 watt.
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) adopted a standard for safe levels of human
exposure to RF energy. Approximately 120 scientists, engi-
neers, and physicians from universities, government, and
industry developed the standard. In March 1993, the Fed-
eral Communications Commission (FCC) proposed the
adoption of the standard. The design of your phone com-
plies with the updated standard. RF exposure can be further
limited by controlling the duration of calls and operating
the phone in a power efficient manner.
Efficient Phone Operation
Extend the antenna fully to operate at the lowest power
level possible. Calls can be sent and received with the
antenna retracted; however, the phone operates more effi-
ciently with the antenna fully extended. Hold the cellular
phone in the same manner as a standard telephone is held.
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 operate at a
higher power level than is necessary.
