WARNING
When conducting maintenance work, make sure to turn
off the power and unplug the power line of the
processor 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.
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.
Turn off the main power source before starting
maintenance.
Otherwise, an electric shock or injury may be caused.
Turn off the main power if you need to be near the
scanner unit for maintenance or inspection purposes.
Direct exposure to electromagnetic waves at close
range in death or serious injury.
