Unit isolation Method
Upon the occurrence of any of the error codes shown above, the defective unit will be cut off from the system (by
software) when you press the [AUTO RESET] key and then switching SW2 (sub power) OFF/ON. Other functions will
remain available. Note that if you don't clear the problem in the defective unit, the error will be detected again (and the
error code displayed again) the next time you turn SW2 OFF/ON. (This cutoff feature is effective one time only.)
