Item Precautions

ESD safe packaging box
After removing a printed board or component, place it in the
antistatic bag or ESD safe packaging box.
Caution
- Do not connect the wrist strap clip to the ESD mat. By connecting the wrist
strap clip to the chassis, the operator and components have the same electrical
potential, thus eliminating the danger of static damage.
