Troubleshooting
Periodic checks and maintenance are important for proper operation of any electronic system. This chapter contains
maintenance and troubleshooting instructions to be followed to obtain optimum performance and the longest
possible life of the equipment. Before attempting any maintenance or troubleshooting procedure please review the
safety information below. If you cannot restore normal operation after following the troubleshooting procedures do
not attempt to check inside any unit; there are no user-serviceable parts inside. Any repair work should be referred to
a qualified technician.
WARNING
Do not open the equipment.
Only qualified personnel should work
inside the equipment.
Turn off the radar power switch before
servicing the antenna unit. Post a
warning sign near the switch indicating
it should not be turned on while the
antenna unit is being serviced.
Prevent the potential risk of being struck by
the rotating antenna and exposure to
RF radiation hazard.
Wear a safety belt and hard hat wh
working on the antenna unit.
Serious injury or death can result if
someone falls from the radar antenna
mast.
The radar antenna emits electromag-
netic radio frequency (RF) energy which
can be harmful, particularly to your
eyes. Never look directly into the
antenna aperture from a close distance
while the radar is in operation or expose
yourself to the transmitting antenna at a
close distance.
NOTICE
Do not apply paint, anti-corrosive
sealant or contact spray to coating
or plastic parts of the equipment.
Those items contain organic solvents
that can damage coating and plastic
parts, especially plastic connectors.
