PROTECTION OF EYES FROM LASER BEAM DURING SERVICING
PICK UP ASSY
: SOLDER
910 15161
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
CONFIRM LASER BEAM EMISSION. BE SURE TO OBSERVE
FROM A DISTANCE OF MORE THAN 30cm FROM THE
SURFACE OF THE OBJECTIVE LENS ON THE OPTICAL
PICK-UP BLOCK.
Caution: Invisible laser radiation when
open and interlocks defeated avoid exposure to beam.
Advarsel:Usynling laserståling ved åbning,
når sikkerhedsafbrydere er ude af funktion.
Undgå udsættelse for stråling.
VAROITUS!
Laiteen Käyttäminen muulla kuin tässä käyttöohjeessa mainitulla tavalla saattaa altistaa käyt-täjän turvallisuusluokan 1 ylittävälle 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
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.

Precaution to replace Optical block
(SF-P200)
Body or clothes electrostatic potential could ruin
laser diode in the optical block. Be sure ground
body and workbench, and use care the clothes
do not touch the diode.
1) After the connection, remove solder shown in
the right figure.

The servo circuit of this model is designed to be adjustment-free and the adjustment value and disc distinction (CA-DA. CD-R and CDRW etc.) is adjusted by within the IC. Therefore the adjustment is performed by each TOC reading. The adjustment conditions within the
IC of each servo can be monitored in this test mode.
1. How to start the Test Mode
Starting method of the test mode differ depending upon the type of disc being used. This is because the adjustment values of each
servo also differ depending upon the type of disc.
When using the CD-DA or CD-R
1) Short-circuit the test land and the OPEN/CLOSE SW land.
2) Insert the AC plug and install the CD-DA or CD-R disc.
3) Press the PLAY and STOP buttons in this sequence and read the TOC.
4) Press the DISPLAY/ENTER button and confirm that all LCD light up.
When using the CD-RW
1) Short-circuit the test land and the OPEN/CLOSE SW land.
2) Insert the AC plug and install the CD-RW disc.
3) Press the PLAY, STOP and DSL buttons in this sequence and read the TOC. The LCD display should display CD-r at this point.
4) Press the DISPLAY/ENTER button and confirm that all LCD light up.
Note 1) If the TOC cannot be read, press the DISPLAY/ENTER button once “Err” has appeared on the LCD, causing all the LCDs to
become lit up. The following steps 2 and 3 can be confirmed even if the TOC cannot be read.
Note 2) By repeatedly pressing the DISPLAY/ENTER button, all LCD will light up and the TOC display will be repeated.
Note 3) By repeatedly pressing the DSL button, the “CD-d” and “CD-r” displays will be repeated.
When the LCD displays “CD-d,” → CD-DA, CD-R is selected.
When the LCD displays “CD-r,” → CD-RW is selected.
Note 4) The test mode is cancelled by disconnecting the AC plug and removing the soldering of short land.
2. DISC distinction (confirmation of FE waveform)
This mode is possible to perform a confirmation of the disc distinction.
Confirmation method
1) Press the DSL button and select “CD-d” or “CD-r” (Refer to Note 3).
2) Install the disc.
3) Press the MODE button.
The LCD will change as follows.
Example: Test disc: TCD-782, DISC type select: CD-d, Judgement value: 7F, Measurement value: 3D BE.
Judgement value Measurement value
*All numerical values are displayed in HEX
What disc the IC has selected can be understood according to this judgment value.
The decision standard of IC is as follow.
LCD displays “CD-r”
LCD displays “CD-d”
0 < Judgment value < 10 No disc No disc
10 < Judgment value < 32 CD-RW No disc
32 < Judgment value < C8 CD-DA and CD-R CD-RW
C8 < Judgment value CD-DA and CD-R
The state of the FE waveform can also be understood from this judgment value.
3. Confirmation of sled movement
By pressing the F. SKIP or B. SKIP button continuously when all LCD light up, it is possible to transfer the pick-up to either the outer
circumference or the inner circumference (the LCD is to remain all light up).

4. Confirmation of the RF level
Test point: RF and VC (Vref)
Test disc: TCD-782
Confirm that the RF waveform appears as shown below.
VOLT/DIV: 200mV
TIME/DIV: 0.5us
At 0.8 Vp-p or greater
5. Confirmation of tracking balance
Test point: TE and VC (Vref)
Test disc: TCD-782
Press the DSL button while the test disc is playing and confirm that the traverse waveform is as is shown below.
VC
VOLT/DIV: 200mv
TIME/DIV: 2ms
6. Confirmation of each servo
It is possible to confirm the adjustment value of each servo by repeatedly pressing the MODE button while the test disc is playing. The
switchover sequence is as stated below.
Confirmation mode OFF -> Focus bias (FB) -> Tracking balance (TB) -> Tracking gain (TG) -> Tracking error offset (TEO) -> Focus
gain (FG) -> Focus error offset (FEO) -> Confirmation mode OFF
Example: Tracking error offset (TEO) Adjustment value-> 03
Tracking error offset (TEO) display Adjustment value
*Adjustment values are displayed in HEX.
