1) Precautions

• This unit uses a single power supply (+5V) for the reg­ulator. The signal reference potential, therefore, is
connected to REFO(approx. 2.5V) instead of GND.
If REFO 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 REFO and GND together. It is especially
important not to connect the channel 1 negative
probe of the oscilloscope to REFO 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 REFO 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.

• Disc detection during loading and eject operations is
performed by means of a photo transistor in this
unit.Consequently, if the inside of the unit is exposed
to a strong light source when the outer casing is
removed for repairs or adjustment, the following mal­functions may occur.

*During PLAY, even if the eject button is

pressed,the disc will not be ejected and the unit
will remain in the PLAY mode.

*The unit will not load a disc.
When the unit malfunctions this way, either re-posi­tion the light source, move the unit or cover the photo
transistor.

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).

• Jump operation of TRs other than 100TR continues
after releasing the key. CRG move and 100TR jump
operations are brought into the “Tracking close” sta­tus when the key is released.

• Powering Off/On resets the jump mode to “Single TR
(91)”, the RF AMP gain setting to 0 dB, and the 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 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.

• 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 track searching taking a long time, may appear.

• 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 ] 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 2 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".

7.2.2 TEST 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.

8-digit display 6-digit display 4-digit display

ERROR–xx ERR–xx E–xx

OR

Err–xx

(2) Error Code List

Code Class Displayed error code Description of the code and potential cause(s)
10 Electricity Carriage Home NG CRG can't be moved to inner diameter.

CRG can't be moved from inner diameter.

→ Failure on home switch or CRG move mechanism.

11 Electricity Focus Servo NG Focusing not available.

→ Stains on rear side of disc or excessive vibrations on REWRITABLE.

12 Electricity Spindle Lock NG Spindle not locked. Sub-code is strange (not readable).

→ Failure on spindle, stains or damages on disc, or excessive vibrations.

Subcode NG A disc not containing CD-R data is found. Turned over disc are found,

though rarely.

→ Failure on home switch or CRG move mechanism.

RF AMP NG An appropriate RF AMP gain can't be determined.

→ CD signal error.

17 Electricity Setup NG APC protection doesn't work. Focus can be easily lost.

→ Damages or stains on disc, or excessive vibrations.

30 Electricity Search Time Out Failed to reach target address.

→ CRG tracking error or damages on disc.

A0 System Power Supply NG Power (VD) is ground faulted.

→ Failure on SW transistor or power supply (failure on connector).

Remarks: Mechanical errors are not displayed (because a CD is turned off in these errors).

Unreadable TOC does not constitute an error. An intended operation continues in this case.
A newly designed head unit must conform to the example given above.
Upper digits of an error code are subdivided as shown below:
1x: Setup relevant errors, 3x: Search relevant errors, 3x: Search relevant errors, Ax: Other errors.

DEH-2000R,2030R,2020R

- New Test Mode

S-CD plays the same way as before.
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 (it varies between the products).
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).

Audio Menu Functions

The Audio Menu features the following functions.

Balance Adjustment (FADER)

This function allows you to select a Fader/Balance setting that provides ideal listening con­ditions in all occupied seats.

1. Press the AUDIO button and select Fader/Balance mode (FADER) in the
Audio Menu.

Note:

• “FADER 0” is the proper setting when 2 speakers are in use.

Equalizer Curve Adjustment (EQ-LOW/MID/HIGH)

You can adjust equalizer curve settings as desired. Adjusted equalizer curve settings are
memorized in “CUSTOM”.

1. Press the AUDIO button and select the Equalizer mode
(EQ-LOW/MID/HIGH) in the Audio Menu.

Note:

• If you make adjustments when a curve other than “CUSTOM” is selected, the adjusted curve is

stored in memory as a “CUSTOM” curve. Also, the displayed curve switches to that selected before
adjustments were made.

3. Boost or attenuate the selected
band with the 5/∞ buttons.

The display shows “+6” – “–6”.

2. Select the band you want to

adjust with the 2/3 buttons.

EQ-LOW += EQ-MID += EQ-HIGH

3. Adjust left/right speaker bal-

ance with the 2/3 buttons.

“BAL L 9” – “BAL R 9” is displayed
as it moves from left to right.

2. Adjust front/rear speaker bal-

ance with the 5/∞ buttons.

“FADER F15” – “FADER R15” is
displayed as it moves from front to
rear.

Equalizer Curve Fine Adjustment

You can adjust the center frequency of each equalizer curve band (LOW/MID/HIGH) and
the Q factor (curve characteristics).

1. Press the AUDIO button for 2 or more seconds to select Equalizer Curve
Fine Adjustment.

Loudness Adjustment (LOUD)

The Loudness function compensates for deficiencies in the low and high sound ranges at
low volume. You can select a desired Loudness level.

1. Press the AUDIO button and select the Loudness mode (LOUD) in the Audio
Menu.

3. Select the desired level with the
2/3 buttons.

LOW += MID += HI

2. Switch the Loudness function
ON/OFF with the 5/∞ buttons.

4. Select the desired Q factor with
the 5/∞ buttons.

2N += 1N += 1W += 2W

3. Select the desired frequency
with the 2/3 buttons.

LOW: 40 += 80 += 100 += 160 (Hz)
MID: 200 += 500 += 1K += 2K (Hz)

Audio Adjustment

Front Image Enhancer Function (FIE)

The F.I.E. (Front Image Enhancer) function is a simple method of enhancing front imaging
by cutting mid- and high-range frequency output from the rear speakers, limiting their out­put to low-range frequencies. You can select the frequency you want to cut.

1. Press the AUDIO button and select the F.I.E. mode (FIE) in the Audio Menu.

Note:

• After switching the F.I.E. function ON, select the Fader/Balance mode in the Audio Menu, and
adjust front and rear speaker volume levels until they are balanced.

• Switch the F.I.E. function OFF when using a 2-speaker system.

Source Level Adjustment (SLA)

The SLA (Source Level Ajustment) function prevents radical leaps in volume when
switching between sources. Settings are based on the FM volume, which remains
unchanged. (Since the FM volume is the control, SLA is not possible in the FM modes.)
The MW/LW and CD levels can all be adjusted.

1. Compare the FM volume with the volume of the other source.
(e.g. Built-in CD player)

2. Press the AUDIO button, and select the SLA mode (SLA) in the Audio
Menu.

3. Increase or decrease the level
with the 5/∞ buttons.

The display shows “+4” – “–4”.

3. Select the desired frequency
with the 2/3 buttons.

100 += 160 += 250 (Hz)

2. Switch the F.I.E. function
ON/OFF with the 5/∞ buttons.

Precaution:

• When the F.I.E. function is deactivated, the rear speakers output sound of all frequencies, not just
bass sounds. Reduce the volume before disengaging F.I.E. to prevent a sudden increase in vol­ume.
