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. 1.2.1 Grounding to prevent damage by static electricity Static electricity in the work area can destroy the optical pickup (laser diode) in devices such as DVD players.
Page 6
Precautions for Service 1.3.1 Handling of Traverse Unit and Laser Pickup (1) Do not touch any peripheral element of the pickup or the actuator. (2) The traverse unit and the pickup are precision devices and therefore must not be subjected to strong shock. (3) Do not use a tester to examine the laser diode.
