If the station is installed in an “outdoor” cabinet, a thermostatically controlled
heater should be installed in the cabinet to prevent the inside air from falling
below freezing (0
°
C or +32
°
F).
While the station is designed to handle “rugged” environments, an air conditioned
location is preferred and desirable. Air conditioning prolongs component life and
makes maintenance easier on technicians. If air conditioning is used, a closed
system is preferred (with no intake of outdoor air).
2.5 Radiation Hazards
The DB-1000 Digital Station is a “base station repeater” and is intended to have
its antenna installed on a radio tower or other antenna support such that the
center of radiation (the antenna) is not near humans. During installation
planning, care should be taken to research and understand relevant government
radiation regulations and to ensure that the final installation will meet such
regulations. Since every installation is unique, radiation safety is beyond the
scope of this manual. You should consult an engineering professional during the
installation of this station to ensure that your installation will not cause any
radiation hazards.
2.6 Mandatory Safety Instructions to Installers
The minimum safe distance from the transmit antenna for this station to a
person(s) is at least 2.00 meters for general population / uncontrolled exposure
assuming antenna gain is 3.0 dBd referenced to a dipole.
The Federal Communications Commission has adopted a safety standard for
human exposure to RF (Radio Frequency) energy, which is below OSHA
(Occupational Safety and Health Act) limits.
Antenna Minimum Safe Distance
: 2.00 meters
Antenna Gain
: 3 dBd referenced to a dipole.
Antenna Mounting
: The transmit antenna should be fixed-mounted on an
outdoor permanent structure.
Warning
: Maintain a separaion distance from the antenna to a person(s) of at
least 2.00 m for general Population / Uncontrolled Exposure.
