Safety Precaution
HIGH VOLTAGE WARNING
Dangerously high voltages are present within the RADAR scanner unit. There are
no internal connections or adjustments necessary for installation. Only a qualified
radar service technician should remove the cover. Technicians must exercise ex-
treme 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 com-
ponents, ground them with a clip lead.
MICROWAVE RADIATION HAZARD
The microwave energy radiated by a radar antenna is harmful to humans, espe-
cially 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.
MAGNETRON PREHEATING
When starting your RADAR for the first time or when restarting it after a two
month or longer non-operating period, preheat the magnetron at least 30 min-
utes in standby mode.
Please read through this manual before the first operation. If you have any ques-
tions, please contact the Company’s customer service or your local dealer.
