Static Electricity Protection Measures; Ground For Electrostatic Breakdown Prevention - Panasonic SA-BTT405P Service Manual

2.3. Static Electricity Protection Measures

• The laser diode in the traverse unit (optical pick-up) may break down due to potential difference caused by static electricity
of clothes or human body.
So, be careful of electrostatic breakdown during repair of the traverse unit (optical pick-up).

2.4. Ground for Electrostatic Breakdown Prevention

• As for parts that use optical pick-up (laser diode), the optical pick-up is destroyed by the static electricity of the working
environment.
Repair in the working environment that is grounded.
2.4.1. Work table grounding
• Put a conductive material (sheet) or steel sheet on the area where the traverse unit (optical pick-up) is placed, and ground
the sheet.
2.4.2. Human body grounding
• Use the anti-static wrist strap to discharge the static electricity from your body.
2.4.3. When exchanging the Drive
• Before remove the ESD prevention bag, make sure to use the anti-static wrist strap to discharge the static electricity when
replace the Drive.
Note:
The ESD prevention bag is used to replace the original short-circuit point.
It can be removed while placing the Drive.
