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 å bning, 
nå r sikkerhedsafbrydere er ude af funktion. 
Undgå  udsæ ttelse for strå ling.

CD TEST MODE
1-1 How to Activate CD Test Mode
1) Connect 62 pin (test) of IC701 (LC72358N-9910) on 
   MAIN C.B to the 31 pin (VDD) by cable.
2) Connect wire of ACC (red) and BACKUP (yellow) of power supply/speaker connector to DC+12V, 
then connect Ground (black) to -.
When CD test mode is started, all displays will be lighted as shown in the following figure.
Caution when servicing 
(1) How to use extension jig.
Correct between MAIN C.B. and CD mechanisms by extension jigs when checking CD mechanism 
(TN-CCD1001-113J) operation. 
(Refer to the following figure.)
1-2 How to cancel CD Test Mode
1) Disconnect the cable of 62 pin (test) and 31 pin (VDD) of the MAIN C.B
IC701 (LC72358N-9910) and switch on the power.

• Do not insert a Disc when confirming Search Mode
• Press PWR button when cancelling Search Mode. Test Mode will be restored when PWR button is 
pressed once again.
• Insert the “Test Disc” when operating all modes except search mode.
* NOTE 1  : There are CD operations are disable owing to the protection circuit being operated when heat builds up in the driver IC
if the focus search is operated continually for more than 10 minutes. In cases, the power supply should be switched off 
for 10 minutes until heat has been reduced and then re-started.
