- Precautions on Adjustment

• The unit employs a single voltage (+5V) for the
regulator, thus the reference potential of the signal is
RFOUT (approximately 2.5V) rather than GND.
Inadvertent contact of REFOUT and GND during
adjustment can result not only in disabling normal
potential measurement but also in exposing the
pickup to strong impacts due to malfunctioning of the
servo. Therefore, you are requested to observe the
following precautions.

• Make sure that the negative probe of the measuring
instrument is not connected to RFOUT or GND.
Special care must be exercised so that the channel 1
negative probe may not be connected to the
oscilloscope and the channel 2 negative probe to
GND. Since the frame of the measuring instrument is
usually at the same potential as the negative probe,
the frame of the measuring instrument must be
changed to floating status.
When RFOUT is inadvertently connected to GND, you
must immediately turn off the regulator or power
supply.

• The regulator must be turned off before mounting or
dismounting filters or wiring materials.

• You should not start adjustment or measurement
immediately after the regulator is turned on. It is
recommended to run the player for approximately
one minute so that it may stabilize.

• When the test mode is turned on, various protective
functions from the software become unavailable.
Thus, you must make sure that undesirable electric or
mechanical shocks are not be given to the system.

• This model employs a photo-transistor for detecting
discs at their loading or ejection. Thus, if its outer
case is removed during repair work and internal parts
are exposed to light of strong intensity, malfunctions
including the following can result:

∗ The eject button becomes inoperable during play.

Pressing the eject button does not eject a disc and
play is continued.

∗ Loading becomes unavailable.

If a malfunction is recognized, appropriate remedial
actions must be taken. Such actions include
changing the light source position, changing the unit
position and applying a cover to the photo-transistor.

• When you press the EJECT key to eject a disc, you
must not touch any other key until the ejection is
complete.

- Description of the Test Mode

• Turning on the Test Mode
Replace by the CD Mechanism Module into
FX-MG8187ZT/UC or FX-MG8687ZT/UC, and refer to the
above-mentioned model's service manual (CRT3097),
then adjust and do test mode.

• Ending the Test Mode
Apply the reset (the reset will be applied three minutes
after the power is turned from off).

• Note :

The grating angle of the PU unit cannot be adjusted after the PU unit is changed. The PU unit in the CD

mechanism 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 TRACK UP and TRACK DOWN buttons, move the PU unit to the innermost track.

3. Press key 5 to close focus, the display should read "91". Press key 3 to implement the tracking balance
adjustment the display should now read "81". Press key 5 4 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
difference 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
average angle.

• Hint

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

* The spring (A) will be removed with the Clamper

arm.

2. Slide the Clamp UP lever (B) to remove it.

3. Loosen the 2 screws. Remove the feed-screw cover

by sliding it.

4. Remove the feed-screw pressure spring (D).

5. Loosen the 2 screws. Remove the feed-screw holder

(E).

6. Remove the belt.

7. Remove the Pickup unit together with the feed screw.
* Be careful not to lose the shaft holders at the both

ends of the feed screw.

* Be careful not to damage the 2 flexible PCBs(for the

Pickup and motor) when separating them. The
flexible PCBs have been stuck each other with
double-sided adhesive tape.
