[. . . ] Put disc (YEDS-18) in and actuate the focus search. (actuate the focus search when disc table is moving in and out. ) 6. Check the oscilloscope waveform (S-curve) is symmetrical between A and B. And confirm peak to peak level within 4. 5 1 Vp-p. S-curve waveform symmetry A Within 4. 5 1 Vp-p B Procedure : 1. Connect oscilloscpe to test point TP (TE) on BD board. Put disc (YEDS-18) in to play the number five track. Check the level B of the oscilliscope's waveform and the A (DC voltage) of the center of the Traverse waveform. Confirm the following : A/B x 100 = less than 22% Center of the waveform B 7. After check, remove the lead wire connected in step 2 and 3. 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. 0V + 0. 7 0. 6 Vp-p A (DC voltage) level : 1. 3 symmetry 1 track jump waveform RF Level Check oscilloscope BD board TP (RF) TP (VC) TP (TE) TP (VC) BD board oscilloscope E-F Balance Check (With general remote commander) Procedure : 1.
