CAUTION
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.
