9.10 Maintenance
9.10.1 General
maintenance
To operate radar equipment constantly in a good condition, the following maintenance is necessary.
Maintain the equipment periodically. Periodic maintenance reduces failures.
The following common maintenance points are applied to each unit.
1. Cleaning the equipment
Remove dust, stains, and seawater from the cabinet as much as possible. Use a dry cloth for
cleaning.
2. Checking the tightening of screws
Check the tightening of screws of assembly and component setting crews that are used for the
equipment.
3. Checking connections
Check the cable connections between equipment units (scanner unit - processing unit,
processing unit - power, processing unit - keyboard unit, processing unit - display unit,
processing unit - optional equipment) if the equipment units are electrically connected.
Make sure that the main power is turned off before maintaining the equipment.In
particular, when a rectifier is used, a voltage is output from the rectifier even if the
power of the display is turned off and the radar is stopped.
If maintenance work is performed without turning off the main power, there is a risk
of equipments breaking down, and dying or getting a serious injury of any person
by electric shock.
