Human Exposure Compliance RF-Orchestra!™ Transmitter Installation and Operation
xxiv 6880493G02-C July 2000
The above table summarizes the safe distance from the paging station for different powers.
While installation calculations such as the above are useful and essential in planning and
design, validation that the operating facility using this equipment actually complies will
require making power density measurements. For information on measuring RF fields for
determining compliance with the FCC requirements, see IEEE Recommended Practice for the
Measure of Potentially Hazardous Electromagnetic Fields—RF and Microwave, IEEE Standard
C95.3-1991. Copies of IEEE C95.3-1991 may be purchased from The Institute of Electrical and
Electronics Engineers, Inc., Attention: Publication Sales, 445 Hoes Lane, P.O. Box 1331,
Piscataway, NJ 08855-1331, (800) 678-IEEE or from ANSI, [phone]. Persons responsible
for installation of this equipment are urged to consult the standard in determining whether a
given installation complies with the applicable limits.
Whether a given installation meets the requirements of FCC Rules Part 1 section 1.1310 for
human exposure to radio frequency radiation may depend not only on this equipment, but
also on whether the environments being assessed are being affected by radio frequency fields
from other equipment. The effects of this other equipment may add to the level of exposure.
Accordingly, the overall exposure may be affected by radio frequency generating facilities that
exist at the time the licensee's equipment is being installed or even by equipment installed
later. Therefore, the effects of any such facilities must be considered in site selection and in
determining whether a particular installation meets the FCC requirements.
