Adjustment Procedure 1.Switch the regulator on. 2.Using VR1001(TE OFFSET) adjust DC voltage of TEY from REFO to 0±25mV.
Adjustment Procedure 1.Load disc and switch regulator on. 2.Position the PU unit in the center of the disc using the TRK UP and TRK DOWN keys. 3.Press key RPT to close focus and press once more to close spindle. 4.Input the L.P.F. output of E to the X axis, and L.P.F. output of F to the Y axis of an oscilloscope by the AC mode, observe lissajous, and check that the grating is within ±45°. (See Waveform 1�3). 5.If the grating is over 45°, make a fine adjustment by slowly turning the screw driver, so that the lissajous is in line. If, however during the adjustment the screw driver should be turned too much and the lessajous should become out of line, proceed to the next grating adjustment 2.
