6. ADJUSTMENT
6.1 CD ADJUSTMENT
1) Precautions
• This unit uses a single power supply (+5V) for the regulator. 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.
• 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
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 recovery is disabled, the recovery is enabled by resetting a product or turning ACC
off to on.
38
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).

6.2 CHECKING THE GRATING AFTER CHANGING THE PICKUP UNIT
• 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
• Disc

• Checking Procedure
1. In test mode, load the disc and switch the 5V regulator on.
2. The display will change, returning to "81" on the fourth press.
3. 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.
4. 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".

6.3 ERROR 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 (minutes 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.

- How to remove the Control Unit
1. Give jumper-solder treatment to the Flexible Wire of
the Pickup unit, then remove the wire from the
Connector.
2. Remove all 4 points of solder-treatment on the Lead
Wire. Also, unscrew the screw(1 piece).
3. Then, Remove the Control unit.
(Caution)
Be careful not to damage SW when you reassemble
the Control Unit into the device.
