Turn off the main power source before replacing parts.Otherwise, an electric shock or
injury may result.
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 result.
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 CRT.
If only one person does this work, he may drop the CRT, resulting in injury.
Even after the main power source is turned off, some high voltages remain for a while.
When disconnecting the wires of the high-voltage pack from the CRT, do not contact the
core wire (metallic) of the CRT anode cap with bare hands. Otherwise, an electric shock
may result.
