Caution:
International Regulations for Preventing Collisions at Sea man-
date that when radar is on a vessel, the radar must be used at
all times, regardless of weather conditions or visibility. Numer-
ous court decisions have not only ruled the radar must be used,
but that the radar operator must be knowledgeable in all opera-
tional aspects of radar performance or otherwise face a greater
risk of liability if an accident occurs.
Caution:
If you purchased an open array radar antenna, make sure it is
installed in an area free of hardware obstructions and free of po-
tential obstructions like sails, lines or other vessel components
that could intermittently intrude or be caught up in the array
antenna's rotation path.
WARNING: High Voltage Hazard
Dangerously high voltages are present within the radar
scanner unit. The unit contains no user-serviceable
parts. The cover should be removed only by a qualified
radar service technician. Technicians must exercise ex-
treme care when working inside the unit. ALWAYS re-
move 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. There are no internal connections or adjust-
ments necessary for installation.
WARNING: Microwave Radiation Hazard
The microwave energy radiated by a radar antenna is
harmful to humans, especially to the eyes. NEVER look
directly into an open waveguide or into the path of ra-
diation from an enclosed antenna. Radar and other ra-
dio frequency radiation can upset cardiac pacemakers.
If someone with a cardiac pacemaker suspects abnormal
operation, immediately turn off the radar equipment
and move the person away from the antenna. Turn off
the radar whenever it is necessary to work on the an-
tenna unit or other equipment in the beam of the radar.
