4.1.1. Precautions for replacing parts in the scanner unit
Follow the precautions below to carry out parts replacement without getting injured.
Confirm that all the radar equipment (if more than one unit is used) is turned off
before you start the parts replacement. For the sake of safety, turn off the main
power circuit breaker.
Wear gloves to protect your hands during parts replacement. Be very careful not to
drop a tool or part when you work in high places.
Carry out parts replacement while the ship does not roll or pitch much in a bay if
possible.
Be careful that the radiator does not hit anyone during parts replacement. The
radiator can turn with wind or the like.
