                                ERROR CODES

                      Power On Initialization Errors

  On power up, if the LCD screen displays  E  or  EE , check the
  following

            1.If an empty caddy is inserted or partially inserted in the
            drive, remove it and restart the drive.

            2.Turn the drive, disconnect the SCSI I/O cables and then
            turn the drive back on. If the problem still occurs the drive
            is either getting insufficent power or is broken. Check the
            power and if its good, call Tech Support.

                              Diagnostic Mode

  To Start Diagnostic mode

            1.Put any data CD into the caddy and insert the caddy into
            the drive.

            2.Restart the drive while holding the Play/Pause button on
            the front panel

  If there are any problems the error code will be displayed in the LCD
  window, or if no problems are found then ON will be displayed

     Error Codes                            Action

  E0 or E1             Make sure there is a CD in the caddy and that the
                       caddy is fully inserted into the drive. If the
                       problem persists, contact Tech Support.

  E2, E3 or E4         The drive is unable to read the CD. Insure that
                       the CD in the caddy is a data CD, not a audio CD.
                       Try another CD, to determine if the problem is
                       limited to one disc, or the drive. If the problem
                       persists, contact Tech Support.

  E5, E6 or E7         Possible hardware failure, contact Tech Support.
