CD SECTION

Since this CD system incorporates the following automatic
adjustment function, when the pickup is replaced, it is necessary
to reajust it.
Since this CD unit does not need adjustment, the combination
of PWB and laser pickup unit is not restricted.

TEST MODE

Start

Note

Operation

After setting the FUNCTION switch to "CD" turn on power. Not later than 1s but later than 500 msec after power is
turned on press simultaneously the following buttons.

1. CD TEST mode DISC1/2 + DOWN/REVIEW

2. LCD TEST mode DISC1/2 + UP/CUE

3. ELECTRONIC VOLUME TEST mode DISC1/2 + STOP

1. When the CD LID switch is in the OFF position, the unit will be able to enter the test mode.
However, playback cannot be performed in this mode.

2. The LCD lights wholly.
The use of the "UP/CUE" button will move the pickup to the outermost position.

1

The use of the "DOWN/REVIEW" button will move the pickup to the innermost position.
When the "PLAY" button is pressed, the laser will be lit, and when the "STOP" button is pressed, it will be

2

turned off. Playback will also start and stop when these buttons are pressed.
a. If the "PLAY" button is pressed while in the stop mode, the laser will simply be turned on at first.

b. If the laser is lit and the "PLAY" button is pressed again, playback will start from the current pickup position.
c. If the "STOP" button is pressed, playback will stop. When pressed again, the laser will be turned off.

Turning the tracking servo on or off.3
a. Each time the PAUSE button is pressed during playback, the tracking servo will be turned on or off.

(Note: If the PLAY button is pressed while in the stop mode, the tracking servo will automatically be
turned on.)

When the TEST mode is entered, at first the CD mechanism is shifted to Tray 1 or Tray 2.
The CD mechanism can be shifted by using the DISC1/2 button.

TROUBLESHOOTING (CHANGER CONTROL SECTION)

When the changer mechanism fails to operate normally.

Operation failure may be caused by blocking of disc at the changer mechanism tray. Therefore, it is necessary to check at
first to see whether there is any disc blocking.
If no abnormal phenomena were found and the normal operation cannot be resumed, check as follows.

Set the FUNCTION switch to REMOTE ON mode, and set the POWER button to ON.

Set the FUNCTION switch to CD.

Does LCD give an indication?

Yes

Is the tray opened when the OPEN/CLOSE
button is pressed?

Yes

Does the CD mechanism move up and stop
when disc is selected?

Yes

Is "Er" displayed after normal stop?

No

Normal

• CD microcomputer operation failure.

Is +5V applied to the pin 7 of FW751?

Yes

Is +5V applied to the pin 25 (VDD) of IC901?

Yes

Is the oscillation circuit (periphery of XL701)
of IC901 normal?

Yes

Does LCD display appears when the pin 21
(RESET) of IC901 is instantaneously
connected to GND

Check as stated in item "CD MICROCOMPUTER OPERATION FAILURE".

TROUBLESHOOTING (CD SECTION)

When the CD does not function

When the CD section does not operate When the objective lens of the optical pickup is dirty,this section may not operate.Clean
the objective lens,and check the playback operation.When this section does not operate even after the above step is taken,check
the following items.
Remove the cabinet and follow the troubleshooting instructions.
"Track skipping and/or no TOC(Table Of Contents) may be caused by build up of dust other foreign matter on the laser pickup lens.
Before attempting any adjustment make certain that the lens is clean. If not, clean it as mentioned below."

Turn the power off.
Gently clean the lens with a lens cleaning tissue and a small amount of isopropyl alcohol.
Do not touch the lens with the bare hand.

NOTES ON SCHEMATIC DIAGRAM

• Resistor:
To differentiate the units of resistors, the 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 an
ohm resistor. The resistor designated "Fusible" is a fuse type
resistor

• Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means micro-micro-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

• The indicated voltage in each section is the one measured by
Digital Multimeter between such a section and the chassis
with no signal given.
