Hi I need servicing manuals with circuit and cleaning /alignment
details for the CD and sensor. I also need other ifo on optic input.

The CD player skips tracks and may
be out of adjustment for track sensing or failed optics.
It may just need cleaning or setup instructions and circuit inf.

I also need specs for the audio by optical-digital input
and information on setup and use of the optical-digital input
port and system controls to record or play from that.

Nothing in users manual.

I shall be using it with a Digital radio tuner with optical
output. No inf on digital input spec in users manual.
