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.
s Caution: Invisible laser radiation when
open and interlocks defeated avoid
exposure to beam.
s Advarsel: Usynlig laserståling ved åbning,
når sikkerhedsafbrydere er ude af funktion.
Undgå udsættelse for stråling.
VAROITUS!
Laiteen Käyttäminen muulla kuin tässä käyttöohjeessa
mainitulla tavalla saataa 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 herin may result in
hazardous radiation exposure.
ATTENTION
L’utillisation 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.

TEST MODE
The operations are displayed by LCD of the remote controller.
The keys of the main unit and remote controller can control shifts between operations.
* TEST MODE will ignore any abnormalities during operations. Plug off the power supply once any abnormalities are detected.
* HOLD switch of the remote controller will function in TEST MODE.
TEST MODE
1. How to activate and cancel Test Mode
(1) How to activate
Turn ON the power supply (set batteries) while pressing "VOL-" keys of the both main unit and remote controller.
Once Test Mode is activated, LCD will all light up and EL backlight will be turned ON.
Then it displays "Engineer MODE".
(2) How to cancel
Turn OFF the power supply to cancel Test Mode.
LCD Display when Test Mode is activated.
2. TEST MODE operations
There are 0~13 Test Modes, which are in the order of playback operations. These modes may be selected using VOL+/- keys, while they can be
started or stopped by pressing PLAY key. If a Test Mode is selected, a data will be displayed in "$XXXX".
* The values displayed in "$XXXX" are just IC internal data and their numerical values are of no significance (except for that of No.0, 13)
If any abnormalities were detected during the operation, it displays "Failed".

(1) Checking Laser Power
The display will repeat the string of OFF-> PIT Laser Power -> GRV Laser Power -> OFF every time DISP/SEARCH key of the remote
controller is pressed.
* Laser will not be luminescent.
• LCD Display
PIT Laser Power "LDPP $XX"
GRV Laser Power "LDPG $XX"
(2) Checking Sled Operation
Sled operation can be checked between Mode No. 0, 5~12.
Press F-SKIP to shift the pick-up towards the external circumference.
Press B-SKIP to shift the pick-up towards the internal circumference.
(3) Checking Switch Operation
OPEN/CLOSE SW and HOLD SW on a disc holder can be checked on LCD of the remote controller.
• Light up when the disc holder is closed.
• Alarm mark will light up when HOLD SW on the main unit is turned ON. While POWER SAVE is on, "–" will light up.

MAIN circuit board Test Points
(1) How to activate
Turn ON the power (set batteries) while shorting TP1 of the main circuit board. Once Adjustment Mode is activated,
LCD will all light up and EL backlight will be turned ON.
Then it displays "Manufacture MODE".
Press "PLAY/STOP" key twice to display "IDLE".
(2) How to cancel
Turn OFF the power supply to cancel Adjustment Mode.
(3) Disc to be used
PIT disc (pre-mastered disc): TEST DISC (TGYS1)
GRV disc (MO disc): SONY MDW-74 (fully recorded)
– 28 –
(4) Note
• If a disc had any stains or scars on, the adjustment may not be completed.
• Always place the main unit with its cassette cover upward for adjustment.
• Do not make any manual adjustments.
• If the adjustment is incomplete, it displays "NO ADJ" during normal operation.
(5) Prohibitions
Do not press DSL key of the remote controller. If it was pressed, the mode will change to factory shipment mode.
If any data is changed in this mode, the unit will not be able to function normally.
If accidentally change into this mode, initialize EEPROM and re-do all the adjustments.
2. Adjustment Procedures
(1) PIT Disc (TEST DISC: TGYS1)
Insert the disc and press "PLAY" key (make sure to place main unit with its cassette cover upward).
LCD of the remote controller will be displayed "AUTO ADJ H" first, then "COMPLEAT"
(2) GRV DISC (SONY MDW-74)
Insert the disc and press "PLAY" key (make sure to place main unit with its cassette cover upward).
LCD of the remote controller will be displayed "AUTO ADJ L" first, then "COMPLEAT"
* If it displayed "Failed" during adjustment, it means that some abnormalities are deteced and the operation is
terminated.
(3) Checking RF Level and Error Rate
a)Press "–" key of the remote controller. Display "032c 00e" and playback.
Check the RF waveform (TP3) with an oscilloscope and it is within the 1.0±0.2Vp-p. If it
is not, follow the instruction below to make an adjustment.
• If the value is higher than 1.2Vp-p, short TP4.
• If the value is lower than 0.8Vp-p, short TP5.
b) Press "+" of the remote controller. Display "600c 00e" and playback.
Make sure if the error note is below "60e".
3. Others
(1) EEPROM Initialization
Press "DISPLAY" key, while it displays "IDLE", to start initialization of EEPROM.
Once the initialization is completed, LCD displays "EP INIT OK".
• Re-adjustments are required after every initialization. Otherwise it displaysÅuNO ADJUST!Åvduring the normal
operation.
(2) Checking Sled Operation
Press "F-SKIP" key, while it displays "IDLE", to shift puck-up towards the external circumference.
Press "B-SKIP" key, while it displays "IDLE", to shift puck-up towards the internal circumference.
