REPLACEMENT OF MAJOR PARTS

The system includes parts that need periodic replacement. The parts should be replaced as scheduled.
Use of parts over their service life can cause a system failure.
Turn off the main power source before replacing parts.
Otherwise, an electric shock or trouble may be caused.
Before replacing the magnetron, turn off the main power
source and wait for 5 minutes or more until the high
voltage circuits are discharged.
Otherwise, an electric shock may be caused.
Take off your wrist watch when bringing your hands close
to the magnetron.
Otherwise, your watch may be damaged because the
magnetron is a strong magnet.
Two or more persons shall replace the liquid crystal
monitor. If only one person does this work, he may drop
the LCD, resulting in injury.
Even after the main power source is turned off, some high
voltages remain for a while.
Do not contact the inverter circuit in the LCD with bare
hands. Otherwise, an electric shock may be caused.
