Safety Precautions - Sony CM-B1200 Operating Instructions Manual

Safety precautions

IMPORTANT
For safe and efficient
operation of your phone,
observe these guidelines.
Your dual band (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 band 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 in analog mode, and 1851
MHz to 1989 MHz in digital
CDMA mode. 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.
