[. . . ] Connect test point TP301 (ADJ) on MAIN board to ground with lead wire. Turn Power switch on to set the ADJ mode. Check the oscilloscope waveform (S-curve) is symmetrical between A and B. And confirm peak to peak level within 3±1 Vp-p. S-curve waveform symmetry TP (TE) TP (VC) A within 3 ± 1 Vp-p B Procedure : 1. Connect oscilloscpe to test point TP (TE) on BD board. Connect the test point TP301 (ADJ) on MAIN board to the ground with a lead wire. Turn the Power switch on to set the ADJ mode. Put disc (YEDS-18) in to play the number five track. (The tracking servo and the sledding servo are turned OFF. ) 6. 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% Traverse waveform Center of the waveform B 6. After check, remove the lead wire connected in step 2. 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. RF Level Check oscilloscope BD board TP (RF) TP (VC) 0V A (DC voltage) level : 1. 3 ± 0. 6 Vp-p 7. (The tracking servo and sledding servo are turned ON. ) Confirm the C (DC voltage) is almost equal to the A (DC voltage) is step 6. Traverse waveform Procedure : 1. Connect oscilloscope to test point TP (RF) on BD board. Put disc (YEDS-18) in to play the number five track. Confirm that oscilloscope waveform is clear and check RF signal level is correct or not. 0V C (DC voltage) Tracking servo Sledding servo OFF Tracking servo Sledding servo ON 8. Disconnect the lead wire of TP301 (ADJ) connected in step 1. -- 19 -- RF PLL Free-run Frequency Check Procedure : 1. Connect frequency counter to test point TP (PLCK) with lead wire. BD board TP (PLCK) frequency counter 2. Put the disc (YEDS-18) in to play the number five track.
