2. During disassembly, be sure to turn the power off
since an internal IC might be destroyed when a con-
nector is plugged or unplugged.
3. Please checking the grating after changing the ser-
vice pickup unit(see page 37).

For resistors and capacitors in the circuit diagrams, their resistance values or
capacitance values are expressed in codes:
Ex. *Resistors
Code Practical value
123 12k ohms
103 10k ohms
*Capacitors
Code Practical value
103 0.01µF
101/10 100µF/10V
The > mark found on some component parts indicates
the importance of the safety factor of the part.
Therefore, when replacing, be sure to use parts of
identical designation.
Symbol indicates a resistor.
No differentiation is made between chip resistors and
discrete resistors.

1) Precautions
• This unit uses a single power supply (+5V) for the reg-
ulator. The signal reference potential, therefore, is
connected to REFO(approx. 2.5V) instead of GND.
If REFO and GND are connected to each other by mis-
take during adjustments, not only will it be impossi-
ble to measure the potential correctly, but the servo
will malfunction and a severe shock will be applied to
the pick-up. To avoid this, take special note of the fol-
lowing.
Do not connect the negative probe of the measuring
equipment to REFO and GND together. It is especially
important not to connect the channel 1 negative
probe of the oscilloscope to REFO with the channel 2
negative probe connected to GND.
Since the frame of the measuring instrument is usual-
ly at the same potential as the negative probe, change
the frame of the measuring instrument to floating sta-
tus.
If by accident REFO comes in contact with GND,
immediately switch the regulator or power OFF.
• Always make sure the regulator is OFF when connect-
ing and disconnecting the various filters and wiring
required for measurements.
• Before proceeding to further adjustments and mea-
surements after switching regulator ON, let the player
run for about one minute to allow the circuits to stabi-
lize.
• Since the protective systems in the unit's software are
rendered inoperative in test mode, be very careful to
avoid mechanical and /or electrical shocks to the sys-
tem when making adjustment.
• Disc detection during loading and eject operations is
performed by means of a photo transistor in this
unit.Consequently, if the inside of the unit is exposed
to a strong light source when the outer casing is
removed for repairs or adjustment, the following mal-
functions may occur.
*During PLAY, even if the eject button is
pressed,the disc will not be ejected and the unit
will remain in the PLAY mode.
*The unit will not load a disc.
When the unit malfunctions this way, either re-posi-
tion the light source, move the unit or cover the photo
transistor.
2) Test Mode
This mode is used for adjusting the CD mechanism
module of the device.
• Test mode starting procedure
Reset while pressing the 4 and 6 keys together.
• Test mode cancellation
Switch ACC, back-up OFF.
• After pressing the EJECT key, do not press any other
key until the disk is completely ejected.
• If the ] or [ key is pressed while focus search is in
progress, immediately turn the power off (otherwise
the actuator may be damaged due to adhesion of the
lenses).
• Jump operation of TRs other than 100TR continues
after releasing the key. CRG move and 100TR jump
operations are brought into the “Tracking close” sta-
tus when the key is released.
• Powering Off/On resets the jump mode to “1TR”, and
the automatic adjustment value to the initial value.

• Note :
The grating angle of the PU unit cannot be adjusted after the PU unit is changed. The PU unit in the CD mecha-
nism module is adjusted on the production line to match the CD mechanism module and is thus the best adjusted
PU unit for the CD mechanism module. Changing the PU unit is thus best considered as a last resort. However, if
the PU unit must be changed, the grating should be checked using the procedure below.
• Purpose :
To check that the grating is within an acceptable range when the PU unit is changed.
• Symptoms of Mal-adjustment :
If the grating is off by a large amount symptoms such as being unable to close tracking, being unable to perform
track search operations, or taking a long time for track searching.
• Method :
• Measuring Equipment
• Oscilloscope, Two L.P.F.
• Measuring Points
• E, F, REFOUT
• Disc
• ABEX TCD-784
• Mode
• TEST MODE
• Checking Procedure
1. In test mode, load the disc and switch the 5V regulator on.
2. Using the ] and [ buttons, move the PU unit to the innermost track.
3. Press key 3 to close focus, the display should read "91". Press key 2 to implement the tracking balance adjust-
ment the display should now read "81". Press key 3 2 times. The display will change, returning to "81" on the
fourth press.
4. As shown in the diagram above, monitor the LPF outputs using the oscilloscope and check that the phase differ-
ence is within 75° . Refer to the photographs supplied to determine the phase angle.
5. If the phase difference is determined to be greater than 75° try changing the PU unit to see if there is any
improvement. If, after trying this a number of times, the grating angle does not become less than 75° then the
mechanism should be judged to be at fault.
• Note
Because of eccentricity in the disc and a slight misalignment of the clamping center the grating waveform may be
seen to "wobble" ( the phase difference changes as the disc rotates). The angle specified above indicates the aver-
age angle.
• Hint
Reloading the disc changes the clamp position and may decrease the "wobble".

7. GENERAL INFORMATION
7.1 DIAGNOSIS
7.1.1 TEST MODE
- Error Messages
If a CD is not operative or stopped during operation due to an error, the error mode is turned on and cause(s) of the
error is indicated with a corresponding number. This arrangement is intended at reducing nonsense calls from the
users and also for facilitating trouble analysis and repair work in servicing.
(1) Basic Indication Method
1) When SERRORM is selected for the CSMOD (CD mode area for the system), error codes are written to DMIN (min-
utes display area) and DSEC (seconds display area). The same data is written to DMIN and DSEC. DTNO remains
in blank as before.
2) Head unit display examples
Depending on display capability of LCD used, display will vary as shown below. xx contains the error number.

- New Test Mode
S-CD plays the same way as before.
If an error such as off focus, spindle unlocking, unreadable sub-code, or sound skipping occurs after setup, its
cause and time occurred (in absolute time) are displayed.
During setup, operational status of the control software (internal RAM: CPOINT) is displayed.
These displays and functions are prepared for enhancing aging in the servicing and efficiency of trouble analysis.
(1) Shifting to the New Test Mode
1 Turn on the current test mode by starting the reset from the key.
2 Select S-CD for the source through the specified procedure including use of the [SOURCE] key, and inserting the
disc. Then, press the [Jump Mode Selector] key while maintaining the regulator turned off.
3 After the above operations, the new test mode remains on irrespective of whether the S-CD is turned on or off.
You can reset the new test mode by turning on the reset start.
* With some products, the new test mode can be reset through the same operations as that employed for shifting to
the STBY mode (while maintaining the Acc turned off).
