1 2 3 4 How to carry the mecha unit 1. Hold the designated points (shown with dashed lines) of the upper chassis and the front/rear bracket. 2. Be careful not to hold the solid line portions or the CRG mecha part or insert foreign substances, to prevent distortion. 3. When holding the sides of the upper chassis, do not apply excessive force to prevent distortion. (Approx.
5 6 7 8 How to remove the PU unit 1. Create an empty-clamp state according to “How to create empty clamp state (motor drive)”. 2. Hook the feeding screw biasing spring to a tentative hooking portion (Fig 2b). Be careful not to get injured by the spring edge. 3. Hold the PU at the position A as shown in Fig 1. Slide the PU as far as possible toward the holder in the feeding screw so that a joint on the outer end of the feeding screw is loosened. 4.
1 2 3 4 8. EACH SETTING AND ADJUSTMENT 8.1 CD ADJUSTMENT A 1) Cautions on adjustments In this product the single voltage (3.3 V) is used for the regulator. The reference voltage is the REFO1 (1.65 V) instead of the GND. If you should mistakenly short the REFO1 with the GND during adjustment, accurate voltage will not be obtained, and the servo’s misoperation will apply excessive shock to the pickup. To avoid such problems: a.
5 6 7 8 8.2 CHECKING THE GRATING AFTER CHANGING THE PICKUP UNIT A Note : The grating angle of the PU unit cannot be adjusted after the PU unit is changed. The PU unit in the CD mechanism module is adjusted on the production line to match the CD mechanism module and is thus the best adjusted PU unit for the CD mechanism module. Changing the PU unit is thus best considered as a last resort. However, if the PU unit must be changed, the grating should be checked using the procedure below.

5 6 7 8 8.3 PCL OUTPUT CONFIRMATION A - PCL output With the TESTIN (22 pin) status of IC601 to be “H”, it is shifted to PCL Output Test mode after reset started. Check that square wave of 600.0 kHz is output from PCL (8 Pin) of IC601. If clock signal is out of this range, this resonator (X602) must be changed for a new one.
