DEH-1100MPB/XN/EW5 2 1234 1234 C D F A B E SAFETY INFORMATION CAUTION: USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE. 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. Laser diode characteristics Wave length : 785 nm to 814 nm Maximum output : 1 190 µW(Emitting period : unlimited) Additional Laser Caution 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. - 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. CAUTION CLASS 1M INVISIBLE LASER RADIATION WHEN OPEN. DO NOT VIEW DIRECTLY WITH \ OPTICAL INSTRUMENTS 2. During repair or tests, do not view laser beam for 10 seconds or longer. This service manual is intended for qualified service technicians; it is\ not meant for the casual do-it-yourselfer.
