CAUTION
All repairs as described in this troubleshooting guide section are to be performed only after the caution
procedures one through seven listed below have been followed.
1. Check grounding before checking for trouble.
2. Be careful of the high voltage circuit.
3. Discharge high voltage capacitor.
4. When checking the continuity of the switches or 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.

control panel. Always touch yourself to ground while working on this panel to discharge any static charge in
your body.
