PROTECTION OF EYES FROM LASER BEAM DURING SERVICING
VAROITUS!
Laiteen Käyttäminen muulla kuin tässä käyttöohjeessa mainit-
ulla tavalla saattaa altistaa käyt-täjän turvallisuusluokan 1 ylit-
tävälle näkymättömälle lasersäteilylle.
VARNING!
Om apparaten används på annat sätt än vad som specificeras i
denna bruksanvising, kan användaren utsättas för osynling
laserstrålning, som överskrider gränsen för laserklass 1.
Caution: Invisible laser radiation when
open and interlocks defeated avoid expo-
sure to beam.
Advarsel:Usynling laserståling ved åbning,
når sikkerhedsafbrydere er ude af funktion.
Undgå udsættelse for stråling.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.
ATTENTION
L'utilisation de commandes, réglages ou procédures autres que
ceux spécifiés peut entraîner une dangereuse exposition aux
radiations.
ADVARSEL!
Usynlig laserståling ved åbning, når sikkerhedsafbrydereer ude
af funktion. Undgå udsættelse for stråling.
This Compact Disc player is classified as a CLASS 1 LASER
product.
The CLASS 1 LASER PRODUCT label is located on the rear
exterior.
This set employs laser. Therefore, be sure to follow carefully the
instructions below when servicing.
WARNING!
WHEN SERVICING, DO NOT APPROACH THE LASER EXIT
WITH THE EYE TOO CLOSELY. IN CASE IT IS NECESSARY TO

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.
1 RF level check
• Test point: RF & VC
• Test disc: TCD-782
Confirm that the RF waveform as shown below appears.
RF Signal Waveform
EYE PATTERN
must be CLEAR and MAX
1.0±0.2Vp-p
VREF
VOLT/DIV: 200mV
TIME/DIV: 0.5µS
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.
2 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
2) Tracking Balance
When the machine enters the tracking balance check
mode, the following display appears on LCD.
Tracking balance set value

balance
The servo circuit of this model is designed to be adjustment-free
and is automatically adjusted 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 (S801) to the CLOSE (ON) position.
* Alternately, shorting the short land near S801 puts the
switch (S801) to the CLOSE (ON) position.
2) Insert the AC plug to the power outlet.
3) Press PLAY key , then power on, all LCD light turn on.
4) While all LCD light turn on, keep pressing the PLAY
MODE key and short the TEST LAND (TP1) more than
one second.
5) When all LCD lights turn on in step 4), it indicates test
mode has started up.
Note) • Once test mode is started, OPEN/CLOSE switch
can not be accepted.
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 a disc 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. 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.
1) 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.

The tracking balance set value is displayed by
hexadecimal notation in the 16 steps.
Display range of set value: 00 to 0F
Default value of setting (center value): 08
1 Tracking balance check
• Test point: TEO & VC
• Test disc: TCD-782
Press the DSL key while in PLAY MODE then turned
off tracking servo. Confirm that the TE waveform as
shown below appears.

2 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 0F.
(Center value: 08)
3) Tracking Gain (Radial Gain)
When the machine enters the tracking gain check mode,
the following display appears on LCD.

Tracking gain set value
The tracking gain set value is displayed by hexadecimal
notation in the 16 steps.
Display range of set value: 40 to 4F
Default value of setting (center value): 48
1 Tracking gain control check by the manual control
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
TEO waveform on an oscilloscope, the tracking gain
change can be confirmed as follows.
a) Traverse waveform amplitude change
• Test point: TEO & 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.
4. 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 a
glass 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.
