Clean the object lens by an applicator with lens cleaning liquid when the signal level is low than specified value with the following checks. Focus Bias Adjustment Perform this adjustment when the optical pick-up has been replaced or repaired. oscilloscope BD (CD) board TP (RF) TP (VC) + ­ S Curve Check oscilloscope BD (CD) board TP (FEO) TP (VC) + ­ Procedure : 1. Put disc (YEDS-18) in and turned Power switch on again and actuate the focus search. Check the oscilloscope waveform (S-curve) is symmetrical between A and B. (Clear RF signal waveform means that the shape "" can be clearly distinguished at the center of the waveform. ) 5. · RF signal VOLT/DIV: 200 mV TIME/DIV: 500 nS A within 2. 4 ± 0. 7 Vp-p B 6. Note: · Try to measure several times to make sure than the ratio of A : B or B : A is more than 10 : 7. · Take sweep time as long as possible and light up the brightness to obtain best waveform.
