	Check Item		Diagnosis Result
	OPERATION		Check to see if the OPERATION indicator goes on and off when the main
1			switch or breaker is turned on.
	INDICATOR
			(Check the primary and secondary voltage of the transformer.)
2			Check the power supply voltage between 1 and 2. (Refer to the name plate.)
	TERMINAL BLOCK		(Check the primary and secondary voltage of the transformer.)
			Check the fluctuating voltage between 2 and 3. (DC15 to 60 V)
			Check to see if the fuse blows out.
3	FUSE 3.15A
			(Check the R04 of the varistor.)
			Check the voltage at the No. 4 pin on CN13 connector of the infrared receiver.
4	DC5V
			(Check the transformer and the power supply circuit of the rated voltage.)
			Check the voltage at the white lead of the louver motor.
5	DC12V
			(Check the transformer and the power supply circuit of the rated voltage.)
	DC325V		Check the voltage at the No. 1 pin on CN10 connector.
6
	(DC310 to 340V)		(Check the DB01, R05 and C03.)
