Radiofrequency (RF) Energy

Understanding How Your Phone Operates
Your phone is basically a radio transmitter and receiver. When it's turned on, it receives and
transmits radiofrequency (RF) signals. When you use your phone, the system handling your
call controls the power level. This power can range from 0.006 watts to 0.2 watts in digital
mode.
Knowing Radiofrequency Safety
The design of your Centro smart device complies with updated NCRP standards described
below.
In 1991-92, the Institute of Electrical and Electronics Engineers (IEEE) and the American
National Standards Institute (ANSI) joined in updating ANSI's 1982 standard for safety
levels with respect to human exposure to RF signals. More than 120 scientists, engineers
and physicians from universities, government health agencies and industries developed
this updated standard after reviewing the available body of research. In 1993, the Federal
Communications Commission (FCC) adopted this updated standard in a regulation. In
August 1996, the FCC adopted hybrid standard consisting of the existing ANSI/IEEE
standard and the guidelines published by the National Council of Radiation Protection and
Measurements (NCRP).
Body-Worn Operation
To maintain compliance with FCC RF exposure guidelines, if you wear a handset on your
body, use the Palm-supplied or -approved carrying case, holster, or other body-worn
accessory. Use of non-Palm-approved accessories may violate FCC RF exposure guidelines.
Be sure to use an accessory that contains NO metal (snaps, clips, etc.) and provides AT LEAST
1.5 cm of separation between the users body and the unit.
