SAFETY PRECAUTIONS
High Voltage Warning
Dangerously high voltages are present within the RADARpc scanner unit. There are no
internal connections or adjustments necessary for installation. The cover should be removed
only by a qualified radar service technician. Technicians must exercise extreme care when
working inside the unit. Always remove power before removing the cover. Some capacitors
may take several minutes to discharge, even after switching off the radar. Before touching the
magnetron or any high voltage components, ground them with a clip lead.
Microwave Radiation Hazard
The microwave energy radiated by a radar antenna is harmful to humans, especially to one’s
eyes. Never look directly into an open waveguide or into the path of radiation from an
enclosed antenna. Radar and other radio frequency radiation can upset cardiac pacemakers.
If someone with a cardiac pacemaker suspects abnormal operation, immediately turn off the
equipment and move the person away from the antenna. Turn off the radar whenever it is
necessary to work on the antenna unit or on other equipment in the beam of the radar.
