IMPORTANT STATIC ELECTRICITY
PRECAUTIONS
Many of the components in the DR66 are extremely sensitive to static electricity.
The following procedures reduce the possibility of damaging components:
1. Before handling any components or touching anything inside the unit,
discharge your body’s static electric charge by touching a grounded (earthed)
surface. Wear a grounding wrist strap if one is available.
2. Do not remove parts from their antistatic containers or bags until you are ready
to install them. When removing circuit boards (PCBs) or chips from a unit,
immediately place them in an antistatic bag.
3. When handling PCBs, hold them by their edges and avoid touching the
circuitry.
4. Do not slide PCBs or ICs over any surface.
5. Avoid having plastic, vinyl and foam in your work area.
6. Limiting your movements during service work reduces static electricity.
