Page 4 1.5 Safety Precautions (U.K only) (1) This design of this product contains special hardware and many circuits and components specially for safety purposes. For con- tinued protection, no changes should be made to the original design unless authorized in writing by the manufacturer. Replace- ment parts must be identical to those used in the original circuits.
Page 5 Preventing 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. 1.6.1 Grounding to prevent damage by static electricity Static electricity in the work area can destroy the optical pickup (laser diode) in devices such as laser products.
