6. ADJUSTMENT

6.1 CD ADJUSTMENT

1) Precautions

• This unit uses a single power supply (+5V) for the reg-

A

B

ulator. The signal reference potential, therefore, is
connected to VREF(approx. 2.1V) instead of GND.
If VREF and GND are connected to each other by mis­take during adjustments, not only will it be impossi­ble 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 fol­lowing.
Do not connect the negative probe of the measuring
equipment to VREF and GND together. It is especially
important not to connect the channel 1 negative
probe of the oscilloscope to VREF with the channel 2
negative probe connected to GND.
Since the frame of the measuring instrument is usual­ly at the same potential as the negative probe, change
the frame of the measuring instrument to floating sta­tus.
If by accident VREF comes in contact with GND,
immediately switch the regulator or power OFF.

• Always make sure the regulator is OFF when connect­ing and disconnecting the various filters and wiring
required for measurements.

• Before proceeding to further adjustments and mea­surements after switching regulator ON, let the player
run for about one minute to allow the circuits to stabi­lize.

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” sta­tus when the key is released.

• Powering Off/On resets the jump mode to “Single
TR(91)”, the RF AMP gain setting to 0 dB, and the

automatic adjustment value to the initial value.

• 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 sys­tem when making adjustment.

• The RFI and RFO signals are easy to oscillate because

C

D

of a wide band. When observing them, insert a resis­tor of about 1 kΩ to the series.

• This equipment will not guarantee the load ejection
operation when the mechanical unit is turned upside
down. In particular, if the ejection operation is incor­rectly performed and recover
ery is enabled by resetting a product or turning ACC
off to on.

6.2 CHECKING THE GRATING AFTER CHANGING THE PICKUP UNIT

A

• 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, VREF

• 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. 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 wavefor

seen to "wobble" ( the phase difference changes as the disc rotates). The angle specified above indicates the aver­age angle.

m may be

D

• Hint
Reloading the disc changes the clamp position and may decrease the "wobble".

- 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 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 inser

disc. Then, press the [Jump Mode Selector] key while maintaining the regulator turned off.
