The servo circuit of this model is designed to be adjustment-free

and is automaticallyyadjusted inside IC. However, the adjustment

conditions inside IC of the focus bias, tracking balance and

tracking gain can be monitored using the test mode.

1. How to Start the Test Mode,

1) While the main power is OFF, set the OPEN/CLOSE

switch (S109) to the CLOSE (ON) position.

*Alternately, shorting the test lands near S109 puts the

switch (S109) to the CLOSE (ON) position.

2) Insert the AC plug to the power outlet.

3) Insert adisc and chuck the disc. Press the PLAY button

(S106) to enter the PLAY state.

4) While press the PLAY MODE button (S102), connect

the test land to ground through a5600 ohm resistor for 1

second.

S) When all the LCDSturn on, it indicates that the test

mode has started up.

*If the machine cannot enter the PLAY statex

Press the PLAY button to enter the focus search

operation. Perform the step 4) operation while the

machine is performing the focus search operation. Then

the test mode will start.

Note) ●Once the test mode is started and the test land is

grounded through the resistor, key operations of the

machine cannot be accepted.

●While the test mode is established, the OPEN/

CLOSE switch is designed to be ignored.

2. Focus Search Mode

The focus search operation can be checked using this mode.

How to start the focus search mode:

Press the STOP button when the machine is stopped (STOP

mode).

If the STOP button is pressed again, the focus search

operation is stopped.

When adisc is inserted while the machine is in the focus

search mode, the disc does not rotate (focus servo is not

locked ON) but the search operation is repeated.

3. Focus Bias, Tracking Balance and Tracking

Gain Check

Selection of either the focus bias check mode, tracking

balance check mode or the tracking gain check mode can be

made by pressing the PLAY mode key during disc playback.

As the PLAY mode key is pressed, the check mode changes

in the following order.

Check mode OFF -Focus Bias +Tracking Balance

+Tracking Gain

When the mode display appears on the LCD, and when the

PLAY key is pressed in the STOP mode, the LCD shows the

center value at first. Then the display changes to the set

value which is set by the automatic adjustment when the

disc starts rotation.

Focus Bias

When the machine enters the focus bias check mode, the

following display appears on LCD enabling to check the

focus bias setting level inside IC.

Focus bias Bias set value

The bias set value is displayed by hexadecimal notation in

the 64 steps.

Display range of set value 80 to bF

Default value (center value) of setting is displayed as

“9d”. When the value larger than the default value is

displayed, it means that the higher bias value is set to the

machine. When the value smaller than the default value is

displayed, it means that the smaller bias value is set to the

machine,

RF level check

VOLT/DIW 200mV

TIME/DIW 0.5pS

When the mode display appears on the LCD, and when the

PLAY key is pressed in the STOP mode, the LCD shows the

center value at first. Then the display changes to the set value

which is set by the automatic adjustment when the

disc starts rotation,

@Focus bias control by the manual control

The focus bias value can be set to any desired value by

pressing the F. Skip key or B. Skip key during the focus

bias check mode.

The 64 steps can be set in the range from 80 to bF.

(Center value: 9d)

Make an attempt to change the focus bias using the F. Skip

key or B. Skip key while observing the RF waveform on

an oscilloscope, and confirm that the RF signal is

maximum at the default value (the value before starting

the manual operation).

When the maximum amplitude is confirmed at the default

setting, the automatic adjustment works satisfactorily.

Tracking Balance

When the machine enters the tracking balance check

mode, the following display appears on LCD.

Tracking Tracking balance set value

The tracking balance set value is displayed by

hexadecimal notation in the 16 steps.

Display range of set value: 00 to OF

Default value of setting (center value): 08

@Tracking balance control by the manual control

The tracking balance value can be set to any desired value

by pressing the F. Skip key or B. Skip key during the

tracking balance check mode.

The 16 steps can be set in the range from 00 to OF.

(Center value: 08)

When any attempt is made to change the tracking balance

value using the F. Skip key or B. Skip key while observing

the RF waveform on an oscilloscope, the tracking balance

change can be confirmed.

3) Tracking Gain (Radial Gain)

When the machine enters the tracking gain check mode,

the following display appears on LCD.

The tracking gain can be set to any desired value by

pressing the F. Skip key or B. Skip key during the tracking

gain check mode.

The 16 steps can be set in the range from 40 to 4F.

(Center value: 48)

When any attempt is made to change the tracking gain

using the F. Skip key or B. Skip key while observing the

RF waveform on an oscilloscope, the tracking gain change

can be confirmed as follows.

Traverse waveform amplitude change

●Test poinb TPTE &VC

When the tracking gain is changed during the traverse

mode, the waveform amplitude change can be confirmed.

Traverse error signal amplitude change

●Test pointi IC201 Pin @(TAO) &VC

When the tracking gain is changed during the traverse

mode, the waveform amplitude change can be confirmed.

Note) The manual control of the focus bias, tracking

balance and tracking gain can be operated only when

the test mode has started up. Microprocessor

performs all items with automatic adjustment during

the normal CD playback mode so that the manual

operation is not possible. Even when the level setting

is made during the manual operation in the test mode,

the set values are reset when the machine exits the

test mode, and the manually set values are not

memorized too.

Display of Jitter Change Value

The jitter value is displayed during the focus bias check mode.

The “00” display is equivalent to the jitter amount when aglass

disc is played back. The display value shows the actual jitter

deviated from the “00” value. The jitter value is displayed in

the 256 steps from 00 to FF.
