Page 6: Servicing Note
Forced Reset Use this function when the MDS-JA555ES cannot be operated normally due to hung-up of the microprocessor. It is recommended to use this function when you cannot exit the test mode or the retry-cause-display mode, or when the normal operation cannot be performed after the MDS-JA555ES is disassembled once then re-assembled. - Page 7 [BD Board Waveform Check Tool] Use of the exclusive tool (J-2501-149-A) is convenient to check the waveforms on the BD board. GND : Ground terminal I+3V : For measuring IOP (Checking deterioration of the optical pickup laser) : For measuring IOP (Checking deterioration of the optical pickup laser) TEO : TRK error signal (traverse adjustment) : Reference level for when checking signals : RF signal (jitter check)
- Page 8 (BD Board IC171)] The IOP data that is indicated on the optical pick-up, can be saved in the non-volatile memory of the MDS-JA555ES. Saving the IOP data in the memory eliminates the needs to look at the printed value on the label that is attached on the surface of optical pick-up, and enables to view the IOP data on display.
- Page 9 Note: The judgment criterion is shown for the purpose of judging if the performance is acceptable or not. This is not the specification value for adjustment. Use the specification value for adjustment when the MDS-JA555ES is going to be adjusted.
