SHOOTING
Periodic checks and maintenance are important for proper operation of any electronic
system. This chapter contains maintenance and troubleshooting instructions to be fol-
lowed 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. Refer any repair work to a qualified technician.
WARNING
Do not open the equipment.
Hazardous voltage which can
cause electrical shock exists
inside the equipment. Only
qualified personnel should
work inside the equipment.
Turn off the radar power
switch before servicing the
antenna unit. Post a warn-
ing 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.
A transmitting radar
antenna emits electromag-
netic waves, which can be
harmful, particularly the
eyes.
Wear a safety belt and hard
hat when working on the
antenna unit.
Serious injury or death can
result if someone falls from
the radar antenna mast.
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.
