  • Page 6: Servicing Note

    Forced Reset Use this function when the MDS-JA333ES 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-JA333ES 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 pick-up laser) : For measuring IOP (Checking deterioration of the optical pick-up 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-JA333ES. 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.
