CHAPTER 1. GENERAL DESCRIPTION

[1] SAFETY PRECAUTION FOR SERVICE MANUAL

Precaution to be taken when replacing and servicing the Laser Pickup.

The AEL (Accessible Emission Level) of Laser Power Output for this model is specified to be lower than Class 1 Requirements. However, the following precautions must be observed during servicing to protect your eyes against exposure to the Laser beam.

1) When the cabinet has been removed, the power is turned on without a compact disc, and the Pickup is on a position outer than the lead-in position, the Laser will light for several seconds to detect a disc. Do not look into the Pickup Lens.

2) The Laser Power Output of the Pickup inside the unit and replacement service parts have already been adjusted prior to shipping.

3) No adjustment to the Laser Power should be attempted when replacing or servicing the Pickup.

4) Under no circumstances look directly into the Pickup Lens at any time.

5) CAUTION - Use of controls or adjustments, or performance of procedures other than those specified herein may result in hazardous radiation exposure.

[2] IMPORTANT SERVICE NOTES (FOR U.K. ONLY)

Before returning the unit to the customer after completion of a repair or adjustment it is necessary for the following withstand voltage test to be applied to ensure the unit is safe for the customer to use.

Setting of Withstanding Voltage Tester and set.

Set name set value Withstanding Voltage Tester Test voltage 4,240 VPEAK

3,000 VRMS Set time 6 secs Set current (Cutoff current) 4 mA Unit Judgment OK: The “GOOD” lamp lights.

3. CD SECTION

• Adjustment

Since this CD system incorporates the following automatic adjustment functions, readjustment is not needed when replacing the pickup. Therefore, different PWBs and pickups can be combined freely.

Each time a disc is changed, these adjustments are performed automatically. Therefore, playback of each disc can be performed under optimum conditions.

Items adjusted automatically

1) Offset adjustment (The offset voltage between the head amplifier output and the VREF reference voltage is compensated inside the IC.)

* Focus offset adjustment

* Tracking offset adjustment

2) Tracking balance adjustment

3) Gain adjustment (The gain is compensated inside the IC so that the loop gain at the gain crossover frequency will be 0 dB.)

* Focus gain adjustment

* Tracking gain adjustment

Notes:

1. Description of the "FM IF Adjustment" is not carried on this Manual. It is because the IF coil in the FM front end section has been best adjusted in the factory so that its further adjustment is not needed at the field. When replacing the FM front end assembly, no adjustment is needed either.

2. The parts in the FM front end section are prepared in a complete unit, so you can't obtain each part individually.

4. CD ERROR CODE DESCRIPTION

Error Explanation

01 When Pickup set inner position, inner switch cannot detect

'ON' level for 10 secs. 10* CAM error. Can't detect CAM switch when CAM is moving. 11* When it detect cam operation error during initialize process. 20* TRAY error. Can't detect TRAY switch when TRAY is mov-

ing. 21* When it detect TRAY operation error during initialize pro-

cess.

31 When it change to CD function, DSP cannot read initial data.

* 'CHECKING'

If Error is detected, 'CHECKING' will be displayed instead of 'ERCD**'. 'ER-CD**' display will only be displayed when error had been detected for the 5th times.

1.1. How to remove the Record/Playback Head (See Fig. 1)

1. When you remove the screws (A1) x 2 pcs and (A2) x 1 pc., the record/playback head can be removed.

1.2. How to remove the Pinch Roller (See Fig. 2)

1. Carefully bend the pinch roller pawl in the direction of the arrow <A>, and remove the pinch roller (B1) x 1 pc., in the direction of the arrow <B>.

NOTE: When installing the pinch roller, pay attention to the spring

mounting position.

1.3. How to remove the Belt (See Fig. 3)

2. CD MECHANISM SECTION

Perform steps 1 to 4 and 11 to 12 of the disassembly method to remove the CD mechanism.(see page 3-3,3-4)

2.1. How to remove the Optical Pickup (See Fig. 1)

1. Remove the screws (A1) x 2 pcs and shaft (A2) x 1 pc.

2. Remove the stop washer (A3) x 1 pc and gear (A4) x 1 pc.

3. Remove the optical pickup.

NOTE: After pulling out the optical pickup connector, wrap the tip of it

with conductive aluminium foil or the like to protect the optical pickup from the static electricity.

2.2. How to remove CD Disc (See Fig. 2~6)

1. When CD is at play position, Rotate reduction gear C clock-wise as shown in Figure 2 Until disk tray is at ‘STOCK’ position, then rotate the gear further to eject the disk tray (Figure 6) so that CD can be removed from the tray.

2. In another case, if CD mechanism is at tray No. 1 play position and to remove CD located in tray No. 3, the procedure is as follows:

If the gear up down board is located at tray No. 1 position, then rotate Reduction gear C clock-wise until Disc tray is at ‘STOCK’ position. Rotate reduction gear D clock-wise (Figure 3) to move the CD mechanism to tray No. 3 position. This is confirmed by checking the gear up down board position Base on the marking as indicated on the main chassis as shown in Figure 4.

• Usually changer is covered with top plate. As for reference purpose, We exclude the top plate for easy viewing. (Figure 5,6)

CHAPTER 6. CIRCUIT SCHEMATICS AND PARTS LAYOUT

[1] NOTES ON SCHEMATIC DIAGRAM

XL-HP535H/HP535E

•Resistor:

To differentiate the units of resistors, such symbol as K and M are used: the symbol K means 1000 ohm and the symbol M means 1000 kohm and the resistor without any symbol is ohm-type resistor. Besides, the one with “Fusible” is a fuse type.

• Capacitor:

To indicate the unit of capacitor, a symbol P is used: this symbol P means pico-farad and the unit of the capacitor without such a symbol is microfarad. As to electrolytic capacitor, the expression “capacitance/withstand voltage” is used.

(CH), (TH), (RH), (UJ): Temperature compensation

(ML): Mylar type

(P.P.): Polypropylene type

• Schematic diagram and Wiring Side of P.W.Board for this model are subject to change for improvement without prior notice.
