NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic breakdown because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic breakdown and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. Laser Diode Properites Material: GaAlAs Wavelength: 780 nm Emission Duration: continuous Laser Output Power: less than 44.6 W* * This output is the value measured at a distance of 200 mm from the objective lens surface on the Optical Pick-up Block. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270 C during repairing. Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). Be careful not to apply force on the conductor when soldering or unsoldering. Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be damaged by heat.

SAFETY-RELATED COMPONENT WARNING!! COMPONENTS IDENTIFIED BY MARK ! OR DOTTED LINE WITH MARK ! ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION.

SECTION 1 GENERAL

DISC MAGAZINE GETTING OUT PROCEDURE ON THE POWER SUPPLY IS OFF Remove the CASE (LOWER) assembly beforehand 1) Press the lever (stop) assy to arrow direction. 2) Removal the magazine assy. Note: Take out the magazine only when the tray is completely within the magazine. If the disk or tray is sticking out, turn on the power and eject the magazine.

Lever (stop) assy

This section is extracted from CDX-505RFs instruction manual.
CAUTION Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the manufacturer. Discard used batteries according to the manufacturers instructions. ADVARSEL! Lithiumbatteri-Eksplosionsfare ved fejlagtig hndtering. Udskiftning m kun ske med batteri af samme fabrikat og type. Levr det brugte batteri tilbage til leverandren. ADVARSEL Eksplosjonsfare ved feilaktig skifte av batteri. Benytt samme batteritype eller en tilsvarende type anbefalt av apparatfabrikanten. Brukte batterier kasseres i henhold til fabrikantens instruksjoner. VARNING Explosionsfara vid felaktigt batteribyte. Anvnd samma batterityp eller en ekvivalent typ som rekommenderas av apparattillverkaren. Kassera anvnt batteri enligt fabrikantens instruktion. VAROITUS Paristo voi rjht, jos se on virheellisesti asennettu. Vaihda paristo ainoastaan laitevalmistajan suosittelemaan tyyppiin. Hvit kytetty paristo valmistajan ohjeiden mukaisesti.

1. INSTALLATION

Note: Follow the assembly procedure in the numerical order given.
OPTICAL PICK-UP COMPLETE ASSY

chuck plate

1 Move the lever (LOCK 3) in direction A, and return it a little in direction B from the position where the chuck plate is moved down to the lower limit. B A 3 stop ring 2.0 (E type)

4 tension spring (DH)

2 optical pick-up complete assy Note: Insert the shaft (A) first.

shaft (A)

GEAR (LOMINI) / (LOAD 1) ASSY

gear (LOAD 2)

2 Attach the gear (LOMINI) at the position shown in Fig. A.
gear (LOMINI) shaft (rotary prevention C) chuck plate
B 1 Move the lever (LOCK 3) fully in direction B to move the chuck plate up.

marking Fig. A

3 Attach the gear (LOAD 1) assy with its facing inside. 4 stop ring 1.5 (E type)

OPERATION CHECK

1 Confirm that the slider moves in direction C to move down the chuck plate if the gear (LOAD 1) is rotated in direction A or the chuck plate moves up and the slider moves in direction D if the gear is rotated in direction B.

2 Engage the slots of slider (R) with the shafts.
ADJUSTING PHASE OF SLIDERS (L, R)
1 Sliding the sliders (L, R) in the arrow direction, meet holes a and b of the sliders (L, R) with holes c and d of the case (LOWER) assy.

4 retaining ring 2 retaining ring 3 gear (ELV 2) 1 gear (ELV 3) Note: After mounting the gear, confirm that the holes for phase adjustment are not shifted. 5 tension spring (STOP LEVER)

2. MECHANICAL ADJUSTMENTS Elevator Height (Address) Adjustment
Note: This adjustments is necessary when the system controller (IC302), variable resistor (RV301), slider (R), slider (L), or chassis (ELV) was replaced for any repair. Connection:
power supply master unit + GND
Adjustment Method: 1. Connect this set to the master unit (e.g. MDX-C670/C670RDS), load a disc magazine, and place the set vertically as shown below. 2. Connect the regulated power supply to the master unit, and turn the power on. 3. Press the DISC button on the master unit and select DISC 5. 4. At this time, if the elevator shaft does not position between comb teeth A and B at addresses 5 and 6 as shown below, adjust the following. 5. Press repeatedly the DISC + and buttons on the master unit so that the elevator shafts moves from address 6 to address 5, or from 5 to 6. At this time, adjust RV301 on the main board so that the elevator shaft positions smoothly between comb teeth A and B.

BUS cable

6. Further, place the set horizontally and make same adjustment as mentioned above. 7. After adjustment at addresses 5 to 6 is finished, check all operations from addresses 1 to 10 with the set placed vertically and horizontally respectively to confirm that the elevator shaft positions in a range between comb teeth A to B.

1. INSTALLATION

Note: Follow the assembly procedure in the numerical order given.
OPTICAL PICK-UP COMPLETE ASSY

chuck plate

1 Move the lever (LOCK 3) in direction A, and return it a little in direction B from the position where the chuck plate is moved down to the lower limit. B A 3 stop ring 2.0 (E type)

4 tension spring (DH)

2 optical pick-up complete assy Note: Insert the shaft (A) first.

shaft (A)

GEAR (LOMINI) / (LOAD 1) ASSY

gear (LOAD 2)

2 Attach the gear (LOMINI) at the position shown in Fig. A.
gear (LOMINI) shaft (rotary prevention C) chuck plate
B 1 Move the lever (LOCK 3) fully in direction B to move the chuck plate up.

marking Fig. A

3 Attach the gear (LOAD 1) assy with its facing inside. 4 stop ring 1.5 (E type)

OPERATION CHECK

1 Confirm that the slider moves in direction C to move down the chuck plate if the gear (LOAD 1) is rotated in direction A or the chuck plate moves up and the slider moves in direction D if the gear is rotated in direction B.

ADJUSTING PHASE OF SLIDERS (L, R)
1 Sliding the sliders (L, R) in the arrow direction, meet holes a and b of the sliders (L, R) with holes c and d of the case (LOWER) assy.

2. MECHANICAL ADJUSTMENTS Elevator Height (Address) Adjustment
Note: This adjustments is necessary when the system controller (IC301), variable resistor (RV301), slider (R), slider (L), or chassis (ELV) was replaced for any repair. Connection:
power supply master unit + GND
Adjustment Method: 1. Connect this set to the master unit (e.g. MDX-C670/C670RDS), load a disc magazine, and place the set vertically as shown below. 2. Connect the regulated power supply to the master unit, and turn the power on. 3. Press the DISC button on the master unit and select DISC 5. 4. At this time, if the elevator shaft does not position between comb teeth A and B at addresses 5 and 6 as shown below, adjust the following. 5. Press repeatedly the DISC + and buttons on the master unit so that the elevator shafts moves from address 6 to address 5, or from 5 to 6. At this time, adjust RV301 on the main board so that the elevator shaft positions smoothly between comb teeth A and B. 6. Further, place the set horizontally and make same adjustment as mentioned above. 7. After adjustment at addresses 5 to 6 is finished, check all operations from addresses 1 to 10 with the set placed vertically and horizontally respectively to confirm that the elevator shaft positions in a range between comb teeth A to B.

SUPPLEMENT-4

Subject: Mechanism Deck Modification (MG-250C-137)

(ENG-98014)

The mechanism deck was changed from MG-250B-137 to MG-250C-137. At the same time, main and jack boards were been changed. This supplement contains only a new type mechanism deck.
