CL ASS 1 L ASER 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. Laser diode characteristics Wave length : 785~814nm Maximum output : 1190µW(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.
