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 servo’s misoperation will apply excessive shock to 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 the mechanism 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 modeThis 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.

• 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 • ABEX 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 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.• 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".

- Error Messages

Error is displayed with number for Error cause when CD is inoperative or stops with Error during operation.The purpose is to reduce nonsense calls from users as well as to assist all related analysis and repair for defects at service station.

(1) Basic Display Method

1) When CSMOD (CD mode area for system) is SERRORM, Error code will be written in DMIN (minutes area for display), DSEC (seconds area for display). The same data shall be written in DMIN and DSEC. DTNO is blank as usual.

2) Display Example of Head Unit

The following is about LCD display ability. xx is Error number.

*) In case of OEM, Error display will follow the specification defined by OEM makers.

8 digits 6 digits 4 digits

ERROR–xx ERR–xx E–xx

(2) Error Code List

No. Classification Contents Details • Cause

10 Electricity Carriage Home NG CRG can’t move to the inner.

CRG can’t move from the inner.

→ HOME SW failure, CRG movement failure.

11 Electricity Focus Search NG Focus can’t be caught.

→ Back of Disc / Severe dirt and vibration.

23 Disc File Format NG Contents are stored in an incompatible file format.

→ The contents in a CD-ROM disc inserted are recorded in a file format other than ISO9660 Level-1 and 2.

22 Disc Impossible to play There is no playable MP3 or WMA file present in a disc.

→ No MP3 or WMA file exists in a CD-ROM disc inserted.

17 Electricity Setup NG AGC protection doesn’t work, out of Focus soon.

→ Scratch on Disc/Severe dirt and vibration.

12 Electricity Spindle Lock NG Not spindle, lock. Wrong subcode (can’t read).

Subcode NG

RF-amp NG

→ Defective Spindle. Scratch and dirt on Disc. Intense vibration.

The appropriate gain of the RF amp cannot be obtained.

→ Defective spindle.

→ Blanc CD-R disc. Disc inserted upside down.

→ Scratched or dirty disc. Severe vibration. Abnormal CD signals.

30 Electricity Search Time Out Can’t reach the target address.

→ Defective CRG/tracking, or scratch on Disc.

→ All TRK Nos. In a disc inserted are specified as a track which should be skipped, in the track skip information.

44 Disc Impossible to play There is no playable TRK No. present in a disc.

50 Mecha Disc Load / Eject NG Disc loading/ejection cannot be complete.

→ Foreign objects entered into the mechanism. Disc caught in between during loading/ejection.

A0 System Power NG Power supply (VD) isn’t connected to the ground.

→ Defective SW transistor. Abnormal power (failed connector)

OR

Err–xx

Note : Error doesn’t display in mechanism only. (CD off causes mechanism off) If TOC can’t be read, error wouldn’t occur, but mechanism still continues its operation. When newly design head unit, be sure to apply as the display examples above. The upper digits of error code is mainly classified by 3 kinds as follows: 1x: Setup related error, 3x: Search related error, Ax: Other errors.

- Removing the Pickup Unit1. Set the mechanism to the clamp mode.2. Remove the lead wires from the inner holder.3. Remove the two washers, styling holder, change arm, and pickup lock arm.4. While releasing from the hook of the inner holder, lift the end of the feed screw.Caution: In assembling, move the planet gear to the load/eject position before setting the feed screw in the inner holder.

- How to hold the Mechanism Unit1. Hold the top and bottom frame.2. Do not squeeze top frame's front portion too tight, because it is fragile.

- Removing the Upper and Lower Frames1. With a disc clamped, remove the four springs (A), the two springs (B), the two springs (C), and the four screws.2. To remove the upper frame, open it on the fulcrum A.3. While lifting the carriage mechanism, remove the three dampers.4. With the frames removed, insert the connectors coming from the main unit and eject the disc.Caution: Before installing the carriage mechanism in the frames, be sure to apply some alcohol to the dampers and set the mechanism to the clamp mode.

Do not squeeze.
