DIAGNOSIS INFORMATION
Outline of self-diagnosis function
This projector is provided with the self-diagnosis function. In case of any failure, the LED at the top of the projector will indicate
the failure. There are two ways for diagnosis.
1
Connect a personal computer to the projector. Then, input [00~CHK] from the hyper-terminal window of the personal
computer during stand-by.
2
Connect a personal computer and click the “diagnosis” button of PCGC8, the diagnostic software to read the warning
history.
Note: Diagnosis can be aiso carried out by turning on the main power and then turning on the power of the operation panel.
However, as the diagnosis items are different and it may cause a secondary failure, carry out the diagnosis in either of the
above-mentioned ways in most cases.
