5.1 Procedure
1 Determine the type of problem.
2 Check for possible user error. Check the connections and the settings of
equipment to determine whether there was a handling mistake.
3 Execute the self diagnostic test by turning the power ON, and identify any
problem items.
4 Analyze the cause of the problem according to the troubleshooting flow chart.
Do not touch the circuit or parts with live voltage because the power unit contains a high-
voltage electrical circuit. The p ower unit is furnished with a dedicated cover to prevent
electric shock. Do not remove this cover. Never touch any part not subject to
adjustment.
Make sure to connect input terminals (voltage or current) correctly. The internal circuit
may be damaged when wrongly connected.
