5 6 7 8 6. ADJUSTMENT A 6.1 CD ADJUSTMENT 1) Cautions on adjustments • In this product the single voltage (3.3V) is used for the regulator. The reference voltage is the REFO1 (1.65V) 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. Do not mix up the REFO1 with the GND when connecting the (-) probe of measuring instruments.
1 A 2 3 4 6.2 CHECKING THE GRATING AFTER CHANGING THE PICKUP UNIT • 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.

This arrangement is intended at reducing nonsense calls from the users and also for facilitating trouble analysis and repair work in servicing.
5 6 8 7 7. GENERAL INFORMATION 7.1 DIAGNOSIS 7.1.1 DISASSEMBLY A - Removing the Case (not shown) 1. Remove the Case. - Removing the CD Mechanism Module (Fig.1) 1 CD Mechanism Module Remove the four screws. B Disconnect the connector and then remove the CD Mechanism Module. 1 1 - Removing the Grille Assy (Fig.1) 2 Release the two latches and then remove the Grille Assy. C 1 1 2 2 Grille Assy Fig.1 - Removing the Tuner Amp Unit (Fig.2) D 1 Remove the screw. 2 Remove the three screws.
1 A 2 3 4 - How to assemble Keyboard Unit 1. Assemble them in order from "1" to "8". (See the figure below.) 2. After that, bend the crows (7 in total) until they get the right angles with the marks printed on "8". Note) If "5" is not set collectly, defective contact may occur on "6". To avoid this problem, hold "5" using "7" just before putting "8".
6 5 8 7 - How to hold the Mechanical Unit A 1. Hold the top and bottom frame. 2. Do not squeeze top frame's front portion too tight, because it is fragile. B Do not squeeze. - Removing the Upper and Lower Frames 1. With a disc clamped, remove the four springs (A), the two springs (B), the two springs (C), and the four screws. 2. To remove the upper frame, open it on the fulcrum A. 3. While lifting the carriage mechanism, remove the three dampers. 4.
1 2 3 4 A Bevel Gear Bracket B - Removing the CD Core Unit(S10) C 1. Apply shorting solder to the Pickup flexible cable. Disconnect the cable. 2. Remove the solder from the four leads, and loosen the screw. 3. Remove the CD core unit(S10). Caution: When assembling the CD core unit(S10), set Shorting Solder the mechanism to the clamp mode to protect the switches from any damage. Solder CD Core Unit(S10) D - Removing the Roller Arm Assy E 1.
5 6 8 7 - Removing the Pickup Unit A Washer 1. Set the mechanism to the clamp mode. 2. Remove the lead wires from the inner holder. 3. Remove the two washers, styling holder, change arm, and pickup lock arm. 4. While releasing from the hook of the inner holder, lift the end of the feed screw. Caution: In assembling, move the planet gear to the load/eject position before setting the feed screw in the inner holder.
