PLEASE READ THESE SAFETY PRECAUTIONS!
RF Energy Health Hazard—FOUR.9 Series
The radio equipment described in this guide employs radio frequency transmitters. Although the
power level is low, the concentrated energy from a directional antenna may pose a health hazard.
Do not allow people to come closer than 119 cm (47.2 inches) to the front of the antenna while
the transmitter is operating. The antenna must be
professionally installed on a fixed-mounted
outdoor permanent structure to provide separation from any other antenna and all persons as
detailed in this manual.
RF Energy Health Hazard—SIX.4 Series
The radio equipment described in this guide employs radio frequency transmitters. Although the
power level is low, the concentrated energy from a directional antenna may pose a health hazard.
Do not allow people to come closer than 3.17 meters (124.80 inches) to the front of the antenna
while the transmitter is operating. The antenna must be
professionally installed on a fixed-
mounted outdoor permanent structure to provide separation from any other antenna and all
persons as detailed in this manual.
Protection from Lightning
Article 810 of the US National Electric Department of Energy Handbook 1996 specifies that radio
and television lead-in cables must have adequate surge protection at or near the point of entry to
the building. The code specifies that any shielded cable from an external antenna must have the
shield directly connected to a 10 AWG wire that connects to the building ground electrode.
