Safety Precautions - Sony D-WAVE Zuma CM Z200 Operating Instructions Manual

Safety precautions

IMPORTANT
For safe and efficient operation of
your phone, observe these
guidelines.
Your dual mode (analog/digital
CDMA) hand-held portable cellular/
PCS telephone uses both analog
frequency modulation (FM) technology
and digital Code Division Multiple
Access (CDMA) technology. CDMA is a
newer radio frequency (RF) technology
than the FM technology that has been
used for radio communications for
decades.
Your dual mode portable cellular/PCS
telephone is a radio transmitter and
receiver. When the phone is ON, it
receives and sends out radio frequency
(RF) energy. The phone operates in the
frequency range of 824 MHz to 894
MHz. When you use your phone, the
cellular/PCS system handling your call
controls the mode of operation (analog
or digital CDMA) and the power level
at which your phone transmits. In the
analog mode, the power is continuously
transmitted at a level that can range
from about 6 mW to about 600 mW. In
the digital CDMA mode, the power is
transmitted as a digitally coded
waveform at a rate varying from 100 Hz
to 800 Hz. The average power can range
from about 0.01 µW to about 300 mW.
Exposure to radio frequency
energy
Research on health effects from RF
energy has focused for many years on
FM radio technology. That research and
studies regarding newer radio
technologies, such as CDMA, have
found no credible scientific evidence
that adverse health effects result from
the use of cellular/PCS telephones.

The Institute of Electrical and
Electronics Engineers (IEEE) in 1991,
and The American National Standards
Institute (ANSI) in 1992, 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, reviewed the available
research and developed this updated
Standard. In March 1993, the U.S.
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:
Your phone has an extendable antenna;
extend it fully whenever possible for
maximum efficiency.
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 operate at a higher power
level than needed.
