- CD Player Service Precautions
1. For pickup unit(CXX1285) handling, please refer
to"Disassembly"(see page 42).
During replacement, handling precautions shall be
taken to prevent an electrostatic discharge(protection
by a short pin).
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).

1) Precautions• This unit uses a single power supply (+5V) for the reg-
ulator. The signal reference potential, therefore, isconnected 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 servowill malfunction and a severe shock will be applied tothe pick-up. To avoid this, take special note of the fol-lowing.Do not connect the negative probe of the measuringequipment to REFO and GND together. It is especiallyimportant not to connect the channel 1 negativeprobe of the oscilloscope to REFO with the channel 2negative probe connected to GND.Since the frame of the measuring instrument is usual-ly at the same potential as the negative probe, changethe 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 wiringrequired for measurements.
• Before proceeding to further adjustments and mea-surements after switching regulator ON, let the playerrun for about one minute to allow the circuits to stabi-lize.
• Since the protective systems in the unit's software arerendered inoperative in test mode, be very careful toavoid mechanical and /or electrical shocks to the sys-tem when making adjustment.
• Disc detection during loading and eject operations isperformed by means of a photo transistor in thisunit.Consequently, if the inside of the unit is exposedto a strong light source when the outer casing isremoved for repairs or adjustment, the following mal-functions may occur.
*During PLAY, even if the eject button ispressed,the disc will not be ejected and the unitwill 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 phototransistor.
2) Test ModeThis mode is used for adjusting the CD mechanismmodule of the device.
• Test mode starting procedureReset while pressing the 4 and 6 keys together.
• Test mode cancellationSwitch ACC, back-up OFF.
• After pressing the EJECT key, do not press any otherkey until the disk is completely ejected.
• If the ] or [ key is pressed while focus search is inprogress, immediately turn the power off (otherwisethe actuator may be damaged due to adhesion of thelenses).
• Jump operation of TRs other than 100TR continuesafter releasing the key. CRG move and 100TR jumpoperations are brought into the “Tracking close” sta-tus when the key is released.
• Powering Off/On resets the jump mode to “1TR”, andthe 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 adjustedPU unit for the CD mechanism module. Changing the PU unit is thus best considered as a last resort. However, ifthe 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 performtrack 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 Procedure1. 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 thefourth 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 anyimprovement. If, after trying this a number of times, the grating angle does not become less than 75° then themechanism 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 beseen to "wobble" ( the phase difference changes as the disc rotates). The angle specified above indicates the aver-age angle.
• HintReloading the disc changes the clamp position and may decrease the "wobble".

6.2 CHECKING THE GRATING AFTER CHANGING THE PICKUP UNIT
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).

Frame, remove two Arms on the front side, then
remove two Tabs on the front side.
- Removing the Carriage Mechanism
1. Disengage the Carriage Mechanism from the two
dampers situated in the front side by driving it up,
then disengage and remove the mechanism from the
one damper by driving it up aslant into front side
direction.
