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 servos 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 orturn 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 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 75try 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 75then 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".

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. DTNOremains 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.

6.6 OEL SCREENSAVER STUDIO LKA TO LKD APPLICATION

6.7 SYSTEM MICROCOMPUTER TEST PROGRAM

"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 (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 outputIn 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.

When you attach Case(CNC8138) in Tuner Amp

Unit, please attach in Tuner Amp Unit, without

also forgetting Insulator(CNM6249).

If you forget to attach Insulator in Tuner Amp

Unit, there is a possibility that the DC/DC ConverterSection may short-circuit.

On the internal surface of the Holder(CND2028),

2 types of spacers(CNM9141, CNM9142) are

affixed for insulation with the OEL unit. When

ordering parts to replace the Holder, please order

the 2 types of spacers along with the 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.

-Removing the Pickup Unit1. 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.
