The>mark found on some component parts indicatesthe 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.
NOTE :
Symbol indicates a capacitor.
No differentiation is made between chip capacitors and

6. ADJUSTMENT6.1 CD ADJUSTMENT
1) Cautions on adjustments
In this product the single voltage (3.3V) is used for the
regulator. The reference voltage is the REFO1 (1.65V)
instead of the GND.
If you should mistakenly short the REFO1 with the GND
during adjustment, accurate voltage will not be obtained,
and the servos misoperation will apply excessive shockto the pickup. To avoid such problems:
a. Do not mix up the REFO1 with the GND when
connecting the (-) probe of measuring instruments.
Especially on an oscilloscope, avoid connecting the (-)
probe for CH1 to the GND.
b. In many cases, measuring instruments have the same
potential as that for the (-) probe. Be sure to set the
measuring instruments to the floating state.
c. If you have mistakenly connected the REFO1 to the GND,
turn off the regulator or the power immediately.
Before mounting and removing filters or leads for
adjustment, be sure to turn off the regulator.
For stable circuit operation, keep the mechanism
operating for about one minute or more after the
regulator is turned on.
In the test mode, any software protections will not
work. Avoid applying any mechanical or electrical
shock to the mechanism during adjustment.
The RFI and RFO signals with a wide frequency range
are easy to oscillate. When observing the signals,
insert a resistor of 1k ohms in series.
The load and eject operation is not guarantied with themechanism upside down. If the mechanism is blocked
due to mistaken eject operation, reset the product or
turn off and on the ACC to restore it.
2) Test mode
This mode is used to adjust the CD mechanism module.
To enter the test mode.
While pressing the 4 and 6 keys at the same time, reset.
To exit from the test mode.
Turn off the ACC and back up.
Notes:
a. During ejection, do not press any other keys than the
EJECT key until the loaded disc is ejected.
b. If you have pressed the () key or () key during focus
search, turn off the power immediately to protect the
actuator from damage caused by the lens stuck.
c. For the TR jump modes except 100TR, the track jump
operation will continue even if the key is released.
d. For the CRG move and 100TR jump modes, the tracking
loop will be closed at the same time when the key is
released.
e. When the power is turned off and on, the jump mode
is reset to the single TR (91), the RF amp gain is set to 0dB,
and the auto-adjustment values are reset to the default
settings.

6.2 CHECKING THE GRATING AFTER CHANGING THE PICKUP UNIT
REFO1E
F
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
Measuring Points
Oscilloscope, Two L.P.F.
E, F, REFO1
Disc TCD-782
Mode TEST MODE
Checking Procedure1. In test mode, load the disc and switch the 3V 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
adjustment 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
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 75try 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 75then the
mechanism should be judged to be at fault.NoteBecause 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.
HintReloading the disc changes the clamp position and may decrease the "wobble".

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
(minutes display area) and DSEC (seconds display area). The same data is written to DMIN and DSEC. DTNOremains in blank as before.

-How to hold the Mechanism Unit
-Removing the Upper and Lower Frames1. With a disc inserted and clamped in the
mechanism, remove the two Springs (A),
the six Springs (B), and the four Screws.2. Turn the Upper Frame using the part "a" as
a pivot, and remove the Upper Frame.
3. While lifting the Carriage Mechanism,
remove it from the three Dampers.
Caution: When assembling, be sure to apply
some alcohol to the Dampers and assemble
the mechanism in a clamped state.
1. Hold the Upper and Lower Frames.
2. Do not hold the front portion of the Upper
Frame, because it is not very solid.

connector.
2. Unsolder the four leads, and loosen the
Screw.
3. Remove the CD Core Unit.
Caution: When assembling the CD Core Unit,
assemble it with the SW in a clamped state
so as not to damage it.
-How to remove the Pickup Unit1. Make the system in the carriage mechanism mode, and have it clamped.
2. Remove the CD Core Unit and remove the leads from the Inner Holder.3. Remove the Poly Washer, Change Arm, and Pickup Lock Arm.
4. While releasing from the hook of the Inner Holder, lift the end of the Feed Screw.
Caution: When assembling, move the Planet Gear to the load/eject position before setting the Feed Screw in the Inner
Holder.
Assemble the sub unit side of the Pickup, taking the plate (Chassis) in-between. When treating the leads of the Load
Carriage Motor Assy, do not make them loose over the Feed Screw.
