Checking or repair by an unqualified person may cause a fire or an electric
shock.
Contact our head office, or a nearby branch or local office to request
servicing.
Never remove the cover of this equipment.
Touching the high-voltage section inside will cause an electric shock.

Otherwise, a fire, an electric shock, or a malfunction may occur.
When conducting maintenance, make sure to turn the main power off.
Failure may result in electric shock.
Turn off all the main powers before cleaning the equipment. Make sure to turn
it off since voltage is still outputted from the rectifier even after the indicator
and the radar are turned off. Failure may result in equipment failure, or death
or serious injury due to electric shock.
When conducting maintenance work on the radar antenna, make sure to turn
all the main powers off.
Failure may result in electric shock or injuries.
