PRECAUTION
1. Check ground before checking for trouble.
2. Be careful of the high voltage circuit
3. Discharge the high voltage capacitor.
4. When checking the continuity of the switches or transformer, disconnect lead wires from these parts and then
check continuity without the power source on. To do otherwise may result in a false reading or damage to
your meter.
5. Do not touch any part of the circuit or the control circuit board, since static discharge may damage it. Always
Touch ground while working on it to discharge any static charge built up.
