• 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.
