Notes:

  • Error codes on MD-MS721H/MS702H according to English speaking service manual:
    • RF side FG, TG, and TCRS adjustment termination failure
    • Adjustment servo retraction excessive retrial
    • A, B, E, F, and TCRSO offset measurement value out of tolerable range
    • Focus retraction completion allowable time-over
    • Track search completion allowable time-over
    • P-TOC read failure
    • U-TOC read failure
    • U-TOC write data write disabled/read check error
    • SD write data disabled
    • Pickup position initialization time-over
    • EEPROM data read check sum error
    • Record head drive displaced (by EJECT lever)
    • Power overvoltage detection
    • Ambient temperature is higher than the allowable temperature
  • Error codes on MD-MS721H/MS722H according to German speaking service manual:
    • RF side FG, TG, and TCRS adjustment termination failure
    • Adjustment servo retraction excessive retrial
    • C-IN recognition time-over
    • A, B, E, F, and TCRSO offset measurement value out of tolerable range
    • Focus retraction completion allowable time-over
    • Track search completion allowable time-over
    • linear disc speed measurement failure
    • P-TOC read failure
    • U-TOC read failure
    • U-TOC write data write disabled/read check error
    • SD write data disabled
    • Pickup position initialization time-over
    • EEPROM data read check sum error
    • Power overvoltage detection
    • Ambient temperature is higher than the allowable temperature
  • MD-MT821 EEPROM settings were taken from my unit (EEPROM version d).
  • MD-MS721/722 EEPROM settings as specified in the EEPROM data list (version f) taken from the German service manual. This manual can be ordered (about 8.50 EUR) from Schaltungsdienst Lange, as far as I know you can get the English manual there as well.
  • MD-MS701/702 EEPROM settings as specified in the EEPROM data list taken from the service manual provided by the Minidisc Community Page (MDCP, MD-MS701 service manual).
  • AUTO1, AUTO2 I haven't tried these modes because I think a high and low reflective test MD (which I do now own) will be needed to complete the adjustments. If you should gain experience with the AUTO1/AUTO2 mode using normal MDs please email what you find out to Forian Rist.
  • T_PLAY, T_REC, INNER, Normal My MT821 reported ´Er.ADJ.´ whenever I tried to enter these modes. I suppose you have to execute AUTO1 and AUTO2 before you will be able to enter these modes.
  • To enter TEST mode on the Sharp portable MD units you have to ensure your unit is in standby mode (press STOP twice) than hold down DISP and BASS and press PLAY. The µC and EEPROM version will be displayed for a second, then the whole display will light up for two seconds. Now the unit is in TEST mode. Please do not enter TEST mode until you know exactly what you are doing. Improper use of TEST mode can seriously damage your unit! Please refer to the information on TEST mode on the Minidisc Community Page. If you should be unable to find what you are looking for feel free to ask me.
