6.3 SYSTEM MICROCOMPUTER TEST PROGRAM
- PCL output
In the normal operation mode (the ACC switched ON, the standby mode cancelled), shift the TESTIN terminal to H.
The clock signal is output from the PCL terminal (Pin 37). The frequency of the clock signal is 312.5kHz that is one 32nd
of the fundamental frequency.
6.4 CD ADJUSTMENT
B
C
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.
D
2) Test mode
This 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.
• 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.

6.5 CHECKING THE GRATING AFTER CHANGING THE PICKUP UNIT
A
• 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.

• 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".

6.6 ERROR MODE
A
- 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.

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.

6.7 OEL SCREENSAVER STUDIO IKA TO LKD APPLICATION :GGV1131
"OEL Screensaver Studio" is an application to create OEL display image file. The customer write the image file on a
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 (GGV1131) is added LKA to LKD file conversion function to original "OEL Screensaver Studio".
A
- How to check:
1. Set up GGV1131 application.
2. Confirm the LKA file (ent_disp.lka) is converted to LKD file correctly or not.
Please see a Readme.txt in the GGV1131 or help file of "OEL Screensaver Studio" for more
information.

AM antenna input high impedance AMANT pin is connected with
an all antenna by way of 4.7µH. (LAU type inductor) A series circuit
including an inductor and a resistor is connected with RF ground for
the countermeasure against the ham of power transmission line.
Ground of antenna block
Input of FM antenna 75Ω Surge absorber(DSP-201M-S00B) is necessary.
