OCT. 2007 Printed in Japan 1 2 3 4 SAFETY INFORMATION A This service manual is intended for qualified service technicians; it is not meant for the casual do-it-yourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained to properly and safely repair complex products such as those covered by this manual. Improperly performed repairs can adversely affect the safety and reliability of the product and may void the warranty. If you are not qualified to perform the repair of this product properly and safely, you should not risk trying to do so and refer the repair to a qualified service technician. B - Safety Precautions for those who Service this Unit. When checking or adjusting the emitting power of the laser diode exercise caution in order to get safe, reliable results. Caution: 1. During repair or tests, minimum distance of 13 cm from the focus lens must be kept. 2. During repair or tests, do not view laser beam for 10 seconds or longer. CAUTION: USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE. C D CLASS 1 LASER PRODUCT WARNING! 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. A specially instructed person should do servicing operation of the apparatus. E Laser diode characteristics Wave length : 785 nm to 814 nm Maximum output : 1 190 W(Emitting period : unlimited) Additional Laser Caution F Transistors Q101 in PCB drive the laser diodes. When Q101 is shorted between their terminals, the laser diodes will radiate beam. If the top cover is removed with no disc loaded while such short-circuit is continued, the naked eyes may be exposed to the laser beam. 2 DEH-2000MPB/XN/EW5 1 2 3 4 5 6 7 8 [Important Check Points for Good Servicing] In this manual, procedures that must be performed during repairs are marked with the below symbol.
