MX-KA6 Safety Precautions 1. This design of this product contains special hardware and many circuits and components specially for safety purposes. For continued protection, no changes should be made to the original design unless authorized in writing by the manufacturer. Replacement parts must be identical to those used in the original circuits.
MX-KA6 Preventing static electricity 1. Grounding to prevent damage by static electricity Electrostatic discharge (ESD), which occurs when static electricity stored in the body, fabric, etc. is discharged, can destroy the laser diode in the traverse unit (optical pickup). Take care to prevent this when performing repairs.
MX-KA6 Important for laser products 5. CAUTION : If safety switches malfunction, the laser is 1. CLASS 1 LASER PRODUCT able to function. 2. DANGER : Invisible laser radiation when open and inter lock failed or defeated. Avoid direct exposure to beam. 6.
