PROTECTION OF EYES FROM LASER BEAM DURING SERVICING
This set employs laser. Therefore, be sure to follow carefully the instructions below when servicing.
CAUTION
Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
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 laserstÂling ved Âbning, nÂr sikkerhedsafbrydere er ude af funktion. Undg udsÊ ttelse for strÂling.
ATTENTION
L?utilisation de commandes, rÈglages ou procÈdures autres que ceux spÈcifiÈs peut entraÓ une dangereuse exposition aux ner radiations.
ADVARSEL!

How to Adjust the Rotating Phase of the Gear, Main Cam
1) Push down the hooking catch of the CHAS. MECH, and remove the TRAY. 2) Align the arrow mark of the Gear, Main Cam with the black round mark of the CHAS, MECHA as shown below. 3) Confirm that the Slide, Mech Cam is located in the right position, then insert the TRAY gently. Caution: If the rotating phase of the Gear, Main Cam is incorrectly adjusted, the chucking operation and tray movement will have malfunction.
Align the arrow mark with the black round mark.

*NOTE 1: There are cases when the tracking servo cannot be locked 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 these cases the power supply should be switched off for 10 minutes until heat has been reduced and then re-started. *NOTE 2: Do not press the or keys when the machine is in the status is active. If they are pressed, playback will not be possible after the status has been canceled. If the or keys are pressed in the status, press the key and return to the start mode (No.1). *NOTE 3: When pressing the or keys, take care to avoid damage to the gears. Because the sled motor is activated when the fi or fl keys are pressed, even when the pick-up is at the outermost or innermost track. 4.Operation Outline The operation of each mode is carried out in the direction of the arrows from the start mode as indicated in the following illustration.

1) Connect an oscilloscope to test points TP1 (TE) and TP3 (VREF). 2) Start up the CD test mode. 3) Insert the test disc TCD-782 (YEDS-18) and enter the traverse mode of the CD test mode. 4) Confirm that the traverse waveform on an oscilloscope is vertically symmetrical as shown in the figure below. 5) After confirming the waveform, release the CD test mode.
1) Connect an oscilloscope to test points TP2 (RF) and TP3 (VREF). 2) Turn on the power switch. 3) Insert test disc TCD-782 (YEDS-18) and play back the second program. 4) Adjust SFR101 so that RF signal of the test point TP2 (RF) is MAX and CLEARREST.
