<When an error is detected by diagnosis>
The Main Power Supply Lamp repeats high-speed blinking after completion of a check in
which an error is detected. (See *1.)
For example, when an error is detected in Check 2, the Main Power Supply Lamp lights out
twice and repeats high-speed blinking (ON/OFF in 0.3 seconds interval).
When an error is detected, be sure to count the number of times the Main Power Supply
Lamp lights out.
For detailed results, see "Error Diagnosis".
*1: When an error is detected, there is a possibility that the Main Power Supply Lamp may not
perform high-speed blinking but perform other operation (continuous light-up, light-out). In
this case, remove and then install the 2 SDRAMs on the Main Controller PCB 1.
If the error is not resolved, execute the remedy of the Check No. which is not completed
normally. (For details, see "Error Diagnosis".)
*2: Although diagnosis time for Check 3, and Check 4 is longer than that of other Checks, it is
correct operation.
*3: When the 2 SDRAMs are not mounted on the Main Controller PCB 1, this diagnosis is not
completed. In this case, install the appropriate 2 SDRAMs.
