5. Location of Controls
6. Preventing static electricity
Electrostatic discharge (ESD), whichoccurs whenstatic electricitystoredinthe body, fabric,
etc. is discharged, candestroythe laserdiode inthe traverse unit (optical pickup). Take care to
prevent this whenperforming repairs.
6.1. Grounding to prevent damage bystaticelectricity
Static electricityinthe work area candestroythe optical pickup (laserdiode) indevices suchas
CD players.
Be careful touse propergrounding inthe area where repairs are being performed.
6.1.1. Ground the workbench
1. Ground the workbench bylaying conductive material (such as a
conductive sheet) or an iron plate over itbefore placing the
traverse unit(optical pickup) on it. (Refer to Fig. 6-1.)
6.1.2. Ground yourself
