CAUTION

!

 

•  Verify proper grounding before checking for trouble. 
•  Be careful of any high voltage circuit. 
•  Do not touch any part of the circuit on the printed circuit board, since static electric discharge may damage the 

control panel. Always touch ground while working on this panel to discharge the static electricity, which may be 
resting on your body.
