LASER KLASSE 1 LUOKAN 1 LASERLAITE KLASS 1 LASERAPPARAT CAUTION Use the MD/CD component system only in accordance with the instruc- tions given in this manual and do not attempt to interfere with the in- terlock switch or make any other adjustment as this may result in exposure to hazardous radiation. SAFTY ORECAUTION FOR SERVICE MANUAL WARNINGS (CD) THE AEL (ACCESSIBLE EMISSION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN CLASS 1 BUT THE LASER COMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING THE LIMIT FOR CLASS 1. THEREFORE IT IS IMPORTANT THAT THE FOLLOWING PRECAUTIONS ARE OBSERVED DURING SERVICING TO PROTECT YOUR EYES AGAINST EXPOSURE TO THE LASER BEAM. 1-WHEN THE CABINET IS REMOVED, THE POWER IS TURNED ON WITDOUT A COMPACT DISC IN POSITION AND THE PICK-UP IS ON THE OUTER EDGE THE LASER WILL LIGHT FOR SEVERAL SECONDS TO DETECT A DISC. DO NOT LOOK INTO THE PICK-UP LENS. 2-THE LASER POWER OUTPUT OF THE PICK-UP UNIT AND REPLACEMENT SERVICE PARTS ARE ALL FACTORY PRE-SET BEFORE SHIPMENT. DO NOT ATTEMPT TO RE-ADJUST THE LASER PICK- UP UNIT DURING REPLACEMENT OR SERVICING. 3-UNDER NO CIRCUMSTANCES STARE INTO THE PICK- UP LENS AT ANY TIME. 4-CAUTION-USE OF CONTROLS OR ADJUSTMENTS, OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE. WARNINGS (MD) The AEL (ACCESSIBLE EMMISSION LEVEL) of the laser power output is less than class 1 but the laser component is capable of emitting radiation exceeding the limit for class 1. Therefore it is important that the following precautions are observer during servicing to protect your eyes against exposure to the laser beam. 1) When the unit case cover is removed and LOADING SW (SW 1956) is turned on and then PLAY SW (SW 1954 mechanism PWB) is turned on in a few second. The laser will light for several second to detect a disk. 2) The laser power output of the pickup unit and replacement service parts are all factory pre-set before shipment. Do not attempt to re-adjust the laser pick-up unit during replacement or servicing. 3) Under no circumstances stare into the pickup lens at any time. 4) If laser optical unit becomes faulty, replace the complete laser optical unit. 5) CAUTION-USE of controls or adjustments, or performance of procedures other than those specified herein may result in hazardous radiation exposure.

Ð 3 Ð MD-X60H WIRING OF PRIMARILY SUPPLY LEADS (FOR U.K. ONLY) Precaution to be taken when replacing and servicing the laser pickup. The following precautions must be observed during servicing to protect your eyesvagainst exposure to the laser. Warning of possible eye damage when repairing: If the AC power plug is connected when the inner cover of the unit is removed, the laser will light up during focus access (about 1 second) (Fig. 3-1). During this operation, the laser will leak from the opening between the magnetic head and cartridge holder (Fig. 3-2). In order to protect your eyes, you must not look at the laser during repair. Before repairing, be sure to disconnect the AC power plug.Figure 3-1 Figure 3-2 Magnetic Head Optical pickup    Optical pickupMechanism Chassis Spindle MotorMagnet Head Laser Beam Cartridge Holder NG: The ÒNGÓ lamp lights and the buzzor sounds.
