Warning when you fix electric components !
Don't touch electrically charged parts, as electric
shock may occur even if they are switched off.
Be sure to wait at least 5 min. after turning off
the power and to confirm the voltage between
the pins between + and - is less than DC10V
with a tester before servicing.

Caution
Do not touch any part of the electric circuit
(including the wiring of thermistor and others),
as it has high voltage against the ground.
Pay attention not to damage the insulated wire
when you tighten the screw, as the exposed wire
may cause electric shock or malfunction.
Do not ground the oscilloscope when you operate.
You might destroy it. Also do not touch any metal
part of the oscilloscope while operating.
