3.1.3 OSHA Safety Standards
The United States Department of Labor, through the provisions of
the Occupational Safety and Health Act, has established an
electromagnetic energy safety standard with applies to the use of
this equipment.
Proper use of this radio will result in exposure below the OSHA
limit.
The following precautions are recommended:
DO NOT operate the transmitter of a fixed radio (base station, radio
paging transmitter RF equipment) when someone is within two feet
(0.6 meters) of the antenna.
DO NOT operate the transmitter of any radio unless all RF
connectors are secure and any open connectors are properly
terminated.
Moreover, all equipment must be properly grounded according to
National & Local Electrical Codes.
3.1.4 Lightning Protection Considerations
Both the Extend-A-Page transmitter and receiver have adequate
protection against high voltages. But, for all external connections,
added protection against lightning attack should be considered.
For transmitters used for high power applications with tower
antenna, the following measures will provide sufficient protection
against minor lightning attacks:
• Keep the antenna tower grounding resistance as low as
possible
• The ground rods should be made of copper clad and at
least eight feet long. Multiple rods should be used over a
single rod, if possible.
• Ground the transmission line sheath at every opportunity.
Also, ground the transmission line where it is supported
on poles and where it enters the building.
• Whenever possible, run at least a part of the
transmission line through a length of grounded conduit.
