CAUTION
Any adjustments must be made by specialized service
personnel.
Failure to comply may result in accidents or equipment
failure.
Make sure to shut off the main power before replacing
parts. Failure to comply may result in electrocution or
equipment failure.
When replacing magnetrons, make sure to shut off the
main power and let the equipment stand for more than 5
minutes to discharge the high-voltage circuit. Failure to
comply may result in electrocution.
Make sure to take off your watch when your hand must get
close to the magnetron.
Failure to comply may result in damage to the watch since
the magnetron is a strong magnet.
Make sure that two or more staff member work together
when replacing the LCD. If only one person attempts to
replace the LCD, he/she may drop it and become injured.
Do not directly touch the inverter circuit of the LCD display
