CAUTION
!
• Verify proper grounding before checking for trouble.
• Be careful of the high voltage circuit.
• Discharge the high voltage capacitor.
• When checking the continuity of the switches or of the high voltage transformer, disconnect one lead wire from
these parts and then check continuity with the AC plug removed. To do otherwise may result in a false reading
or damage to your meter.
• Do not touch any part of the circuit on the printed circuit board, since static electric discharge may damage the
control panel. Always touch yourself to ground while working on this panel to discharge any static charge built
up on your body.
