8.1 ROUTINE MAINTENANCE
For operating the radar equipment in the good conditions, it is necessary to make
the maintenance work as described below. If maintenance is made properly,
troubles will reduce. It is recommended to make regular maintenance work.
Common points of maintenance for each unit are as follow:
• Clean the equipment.
Remove the dust, dirt, and sea water rest on the equipment cabinet with a piece of
dry cloth.
Especially, clean the air vents with a brush for good ventilation.
• Never carry out internal inspection or repair work of the
equipment by users. Inspection or repair work by
unauthorized personnel may result in fire hazard or
electric shock. Ask the nearest branch, business office or
a dealer for inspection and repair.
• Turn off the main power before maintenance work.
Otherwise, an electric shock may result.
• Turn off the main power before cleaning the equipment.
Especially, make sure to turn off the indicator if a rectifier
is used. Otherwise, equipment failure, or death or serious
injury due to electric shock may result, because voltage is
outputted from the rectifier even when the radar is not
operating.
