DISASSEMBLYCaution on DisassemblyFollow the below-mentioned notes when disassemblingthe unit and reassembling it, to keep it safe and ensureexcellent performance:1. Take cassette tape and compact disc out of the unit.2. Be sure to remove the power supply plug from the wall

outlet before starting to disassemble the unit.3. Take off nylon bands or wire holders where they need to

be removed when disassembling the unit. After servicingthe unit, be sure to rearrange the leads where they werebefore disassembling.

4. Take sufficient care on static electricity of integratedcircuits and other circuits when servicing.

Note 1:How to open the changer manually. (Fig. 8-3)1. In this state, turn fully the lock lever in the arrow direction

through the hole on the loading chassis bottom.2. While holding the lock lever, rotate the cam gear anticlockwise

until the cam gear rib engages with the clamp lever. (Fig. 9-1)3. After that, push forward the CD slide holder.

Figure 8-1

Note 2:1. After removing the connector for the optical pickup from the

connector, wrap the conductive aluminium foil around thefront end of the connector remove to protect the opticalpickup from electrostatic damage.

Note 3:1. Be careful not to break the claw of the CD mechanism.2. When fining back the cam gear assembly, let it lock by front

movement.

Since this CD system incorporates the following automaticadjustment functions, readjustment is not needed whenreplacing the pickup. Therefore, different PWBs and pickupscan be combined freely.Each time a disc is changed, these adjustments areperformed automatically. Therefore, playback of each disccan be performed under optimum conditions.

Items adjusted automatically(1) Offset adjustment (The offset voltage between the head

amplifier output and the VREF reference voltage iscompensated inside the IC.)

* Focus offset adjustment * Tracking offset adjustment

(2) Tracking balance adjustment (waveform drawing Fig.13-2 EFBL)

(3) Gain adjustment (The gain is compensated inside the ICso that the loop gain at the gain crossover frequency willbe 0 dB.)

( ) indicates AM< > indicates FM stereo

2. In the main section, a tape is being played back.3. In the deck section, a tape is being played back.

( ) indicates the record state.4. In the power section, a tape is being played back.5. In the CD section, the CD is stopped.

Parts marked with ( ) are important formaintaining the safety of the set. Be sure to replace theseparts with specified ones for maintaining the safety andperformance of the set.

NOTES ON SCHEMATIC DIAGRAM Resistor:

To differentiate the units of resistors, such symbol as K andM are used: the symbol K means 1000 ohm and the symbolM means 1000 kohm and the resistor without any symbol isohm-type resistor. Besides, the one with Fusible is a fusetype.

Capacitor:To indicate the unit of capacitor, a symbol P is used: thissymbol P means micro-micro-farad and the unit of thecapacitor without such a symbol is microfarad. As toelectrolytic capacitor, the expression capacitance/withstandvoltage is used.(CH), (TH), (RH), (UJ): Temperature compensation(ML): Mylar type(P.P.): Polypropylene type
