PROTECTION OF EYES FROM LASER BEAM DURING SERVICING
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.

TEST MODE-2/3
The servo circuit of this model has been designed to be free of adjustments and controlled within the IC. Therefore, adjustments and disk judgement
are performed automatically every time the TOC is read out. The adjustment status of each servo inside the IC can be monitored in this test mode.
1. Startup procedure
1) Short the test land.
2) Insert the AC plug.
3) Press the STOP button. (The test mode starts.)
Note 1) The test mode is canceled by disconnecting the AC plug.
Note 2) The OPEN/CLOSE switch cannot be operated during the test mode.
2. Checking the RF level
Test point: RF & VC (Vref)
Test disk: TCD-782
Play back the disk and confirm that the RF waveform is in the following state:
0.8Vp-p or more
VOLT/DIV:200mV
TIME/DIV:0.5us
3. Checking each servo
The adjustment values of each servo can be checked by pressing the MODE button repeatedly during playback. The switching
procedure is as follows.
Check mode OFF™Vref offset (RO)™focus offset (FO)™tracking offset (TO)™tracking balance (TB)™tracking gain (TG) ™
focus gain (FG)™focus bias (FB)™check mode OFF
Example: Tracking offset (TO) Adjustment value™F5

* Adjustment values are indicated in hexadecimal.
When displaying each mode on the LCD and pressing the PLAY button in the STOP status, the center value is displayed on the LCD.
After the disk starts rotating, the adjustment value that was set during automatic adjustment is displayed. The display range of the
center values and adjustment values of each mode are as follows. There are 256 steps for displaying the values of all modes.

1) Vref offset (RO)
2) Focus offset (FO)
