Handling Precautions For Traverse Deck The laser diode in the traverse deck (optical pickup) may break down due to potential difference caused by static electricity of clothes or human body. So, be careful of electrostatic breakdown during repair of the traverse deck (optical pickup). - Handling of traverse deck (optical pickup) 1.
Page 6
3. Take care not to apply excessive stress to the flexible board (FFC). 4. Do not turn the variable resistor (laser power adjustment). It has already been adjusted. - Grounding for electrostatic breakdown prevention 1. Human body grounding Use the anti-static wrist strap to discharge the static electricity from your body.
Page 7
The traverse deck has a short point shorted with solder to protect the laser diode against electrostatics breakdown. Be sure to remove the solder from the short point before making connections. 5. Precaution of Laser Diode Caution : This product utilizes a laser diode with the unit turned "ON", invisible laser radiation is emitted from the pick up lens.

2. Den werkseitig justierten Einstellregler der Lasereinhit nicht verstellen. 3. Nicht mit optischen Instrumenten in die Fokussierlinse blicken. 4. Nicht über längere Zeit in die Fokussierlinse blicken. ADVARSEL: I dette a apparat anvendes laser. CAUTION! THIS PRODUCT UTILIZES A LASER. USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

Step 2 Remove the top cabinet. Step 3 Remove the T-bracket.
Page 15
Step 5 Turn locating pin on both sides 90°. (Locating pin need not to be bent back.) Step 6 Release the wires CN302, CN303, CN304, CN309 and CN502. Remove rear panel by pulling it backward and lift the rear panel assembly.
Page 16
Step 7 Use a hexagonal wrench and turn clockwise to release the tray. Step 8 Pull the CD tray in the direction shown above.
Page 17
Step 9 Remove the CD lid in the direction of the arrow. Step 11 Release the two catches shown above to remove the front cabinet from the CD traverse unit.
Page 18
Step 12 Connect back the wire to CN302, CN303 and CN304. Use the extension wire (REXX0261) to connect to CN502. Use a FFC wire (REEX0137) to connect CN1 to CN309. 8.1.2. Checking for Panel, Main and Deck P.C.B.
8.2. Main Component Replacement Procedures 1. Replacement of the Traverse Deck Step 1 Follow the procedures in ‘Disassembly of the Traverse Unit’ ( Step 1 - Step 4 )
Page 21
Step 3 Desolder the 4 legs of the 2 motors and pull out the Servo P.C.B. Step 4 Widen the 3 bosses with a flat screwdriver and pull out the 3 pins. Then remove the Traverse Deck. Step 5 Remove the flexible cable CN 701. - Removal of the flexible cable.
Note: Insert a short pin into the flexible cable for traverse unit. - Installation of the CD servo P.C.B. after replacement Step 1 Connect the FFC board. Step 2 Install the CD servo P.C.B. in the traverse deck assembly. Note: Before installing the CD servo P.C.B., move the optical pickup towards the outer edge from the marking (black triangle).
Page 23
Step 2 Remove the wires at CN302, CN303 and CN304 and pull out the Main P.C.B. Step 3 Remove 4 screws fixed to the Power Amplifier IC. Step 4 Unsolder the terminals of Power Amp IC and replace the respective component.
8.3. Disassembly and assembly of the Traverse Unit Step 1 Push the lever from position A to B. Step 2 Pull the stopper (black) in the direction of arrow 1 and push the lever in the direction of arrow 2. Step 3 Push the stpeer (black) down until the white lever eject out.
Page 25
Step 1 Place the traverse unit as shown. Step 2 Press in the lever shaft in the direction of arrow 1 as shown and push the traverse unit into the position in the direction of arrow 2. Step 3 Pull the stopper in the direction of arrow 1 and release the lever in the direction of arrow 2 as shown.
8.4. Disassembly and assembly of the Disc Tray Step 2 With lifting the claw in the direction of arrow 1, draw the clamp SW P.C.B. in the direction of arrow 2. Step 3 Remove the mechanism cover. Step 4 Insert the gear with hexagonal wrench into the hole.
Page 27
Step 5 Rotate the hexagonal wrench in the direction of arrow (clockwise), and then open the disc tray fully. Step 6 Upset the CD changer unit again. Step 7 Release both the claws, and then draw the disc tray. Step 8 With forcing the left guide bar manually because the left guide bar interfers with claw, draw the disc tray.
Page 28
Step 1 Slide the drive rack fully in the direction of arrow. Step 2 Holding the drive rack not to move, install the disc tray.
Page 29
Step 3 Align the drive rack with the driver gear. Step 4 Holding the disc tray manually, rotate the pulley gear in the direction of arrow. Step 5 Rotate the gear 5 or 6 times manually, and then push the disc tray. 9.
