Direct exposure to electromagnetic waves at close range will 
have adverse effects on the human body. When it is necessary to 
get close to the scanner for maintenance or inspection 
purposes, make sure to turn the indicator power switch to "OFF"

Direct exposure to electromagnetic waves at close range will 
have adverse effects on the human body. 
 
When conducting maintenance work, make sure to turn off the 
power so that the power supply to the equipment is completely 
cut off. 
Some equipment components can carry electrical current even 
after the power switch is turned off, and conducting maintenance 
work without unplugging the power connector may result in 
electrocution, equipment failure, or accidents.
