6.3 CD ADJUSTMENT
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 mode
This mode is used to adjust the CD mechanism module.
• To enter the test mode.
While pressing the LIST and EQ 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.

6.4 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
• Oscilloscope, Two L.P.F.
• E, F, REFO1
• Disc • TCD-782
• Mode • TEST MODE
• Checking Procedure
1. 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.
• 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".

6.5 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.
8-digit display 6-digit display 4-digit display

CD-R disc and install it to car audio. This function is similar to PC link-kit (CD-PC1).
"OEL Screensaver Studio" is available to the public on the PIONEER Home Page.
This software (GGV1169) is added LKA to LKD file conversion function to original "OEL Screensaver Studio".
- How to check:
1. Set up GGV1169 application.
2. Confirm the LKA file (ent_disp.lka) is converted to LKD file correctly or not.
Please see a Readme.txt in the GGV1169 or help file of "OEL Screensaver Studio" for more
information.
- PCL output
In the normal operation mode (with the detachable panel installed, the ACC switched ON, the standby mode
cancelled), shift the STEST1 (Pin 86) terminal to H.
The clock signal is output from the PCL1 terminal (Pin 37).
The frequency of the clock signal is 312.500kHz that is one 32nd of the fundamental frequency.
The clock signal should be 312.500kHz ± 13Hz.
If the clock signal is out of the range, the X'tal (X601) should be replaced with new one.

- How to hold the Mechanism Unit
1. 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 Frames
1. 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.

- Removing the Pickup Unit
1. Apply shorting solder to the Pickup flexible cable.
Disconnect the cable.
2. Set the mechanism to the clamp mode.
3. Remove the lead wires from the inner holder.
4. Remove the washer, styling holder, change arm,
and pickup lock arm.
5. 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.

IC201 PAL008A
IC201 incorporates a 4channel power amplifier and a DC/DC converter driver. Current for channels 1 and 2 is
supplied from the BACKUP power supply and current for channels 3 and 4 from the ACC power supply.
This is because when current is supplied with voltage increase in the BACKUP power supply as it is done
conventionally, 10A which is the limit to the vehicle fuse is exceeded.
Thus ACC power supply was enabled to supply current so that there are two power supplies of BACUP and
ACC and output of 60W x 4channel is expressed. Increased voltage (VCC1, VCC2) is controlled individually by
separate DC/DC converters. Therefore, different voltages occur when there is difference between the outputs
from L channel and R channel. A diode was hence connected between VCC1 and VCC2 so that voltage difference
will not occur.
Only one DC/DC converter driver is incorporated in IC201. Therefore, another DC/DC converter driver was
prepared externally to be synchronized with the DC/DC converter driver for IC201 and eliminate noise.
