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 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.
56
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.

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. • 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 • Measuring Points • Disc • Mode
• Oscilloscope, Two L.P.F. • E, F, REFOUT • ABEX TCD-784 • TEST MODE CONTROL UNIT

• 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 ERROR–xx
6-digit display ERR–xx OR Err–xx
4-digit display E–xx

- 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).

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. 2. Adjust front/rear speaker balance with the 5/∞ buttons. “FADER F15” – “FADER R15” is displayed as it moves from front to rear.
3. Adjust left/right speaker balance with the 2/3 buttons. “BAL L 9” – “BAL R 9” is displayed as it moves from left to right. 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. 2. Select the band you want to adjust with the 2/3 buttons. EQ-LOW + = EQ-MID + = EQ-HIGH
3. Boost or attenuate the selected band with the 5/∞ buttons. The display shows “+6” – “–6”. 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.
80
DEH-2000R,2030R,2020R
Equalizer Curve Fine Adjustment You can adjust the center frequency of each equalizer curve band (LOW/MID/HIGH) and the Q factor (curve characteristics).
Level (dB)
Q=2N Center frequency
Q=2W Frequency (Hz)
1. Press the AUDIO button for 2 or more seconds to select Equalizer Curve Fine Adjustment. 2. Press the AUDIO button to select the desired band for adjustment. 3. Select the desired frequency with the 2/3 buttons. LOW: 40 + = 80 + = 100 + = 160 (Hz) MID: 200 + = 500 + = 1K + = 2K (Hz) HIGH: 3K + = 8K + = 10K + = 12K (Hz)
4. Select the desired Q factor with the 5/∞ buttons. 2N + = 1N + = 1W + = 2W
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. 2. Switch the Loudness function ON/OFF with the 5/∞ buttons. 3. Select the desired level with the 2/3 buttons. LOW + = MID + = HI
81
DEH-2000R,2030R,2020R
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. 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.
1. Press the AUDIO button and select the F.I.E. mode (FIE) in the Audio Menu. 2. Switch the F.I.E. function ON/OFF with the 5/∞ buttons.
3. Select the desired frequency with the 2/3 buttons. 100 + = 160 + = 250 (Hz) 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”.
