General Safety Information
Human Exposure Compliance
This equipment is designed to generate and radiate radio frequency (RF) energy
by means of an external antenna. When terminated into a non-radiating RF load,
the base station equipment is certified to comply with Federal Communications
Commission (FCC) regulations pertaining to human exposure to RF radiation in
accordance with the FCC Rules Part 1 section 1.1310 as published in title 47 code
of federal regulations and procedures established in TIA/EIA TSB92, Report on
EME Evaluation for RF Cabinet Emissions Under FCC MPE Guidelines,
Compliance to FCC regulations of the final installation should be assessed and
take into account site specific characteristics such as type and location of
antennas, as well as site accessibility of occupational personnel (controlled
environment) and the general public (uncontrolled environment). This equipment
should only be installed and maintained by trained technicians. Licensees of the
FCC using this equipment are responsible for insuring that its installation and
operation comply with FCC regulations Part 1 section 1.1310 as published in title
47 code of federal regulations.
Whether a given installation meets FCC limits 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 which 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.
FCC OET Bulletin 65 provides materials to assist in making determinations if a
given facility is compliant with the human exposure to RF radiation limits.
Determining the compliance of transmitter sites of various complexities may be
accomplished by means of computational methods. For more complex sites direct
measurement of power density may be more expedient. Additional information
on the topic of electromagnetic exposure is contained in the Motorola Standards and
Guidelines for Communications Sites publication. Persons responsible for
installation of this equipment are urged to consult the listed reference material to
assist in determining whether a given installation complies with the applicable
limits.
In general the following guidelines should be observed when working in or
around radio transmitter sites:
- All personnel should have electromagnetic energy awareness training.
- All personnel entering the site must be authorized.
- Obey all posted signs.
- Assume all antennas are active.
- Before working on antennas, notify owners and disable appropriate
transmitters.
- Maintain minimum 3 feet clearance from all antennas.
- Do not stop in front of antennas.
- Use personal RF monitors while working near antennas.
- Never operate transmitters without shields during normal operation.
- Do not operate base station antennas in equipment rooms.
