CD SECTIONCD ERROR CODE DESCRIPTION
Y AdjustmentErrorState Code
[Servo System Error]Since this CD system incorporates the following automatic
0001Cannot detect Pickup-in SW
adjustment functions, readjustment is not needed when
0002DSP access error
replacing the pickup. Therefore, different PWBs and pickups
[Error during close operation]
can be combined freely.
0101Open/Close SW not functioning (Low ? High)
Each time a disc is changed, these adjustments are
0103Open/Close SW not functioning (High ? Low)
performed automatically. Therefore, playback of each disc
[Error during open operation]can be performed under optimum conditions.

(1) Offset adjustment (The offset voltage between the head[Error during skip operation]
amplifier output and the VREF reference voltage is0302Pickup-in SW is not detected
compensated inside the IC.)0306During Disc 1 search, Open/Close SW or Clamp SW
or Disc SW do not change to low.
* Focus offset adjustment
0307Clamp SW not function (Low ? High)
* Tracking offset adjustment
0308Clamp SW not function (High ? Low)
(2) Tracking balance adjustment (waveform drawing 14

(3) Gain adjustment (The gain is compensated inside the IC
so that the loop gain at the gain crossover frequency will
