How to use a wrist strap
Wear a wrist strap in such a way that the inner metal surface (A in
wrist strap band is in contact with your skin. Connect the clip (B in
directly to the chassis.
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.

Precaution
Wear an antistatic wrist strap when handling printed boards and
components containing electronic components.
An approved ESD mat provides protection from static damage
when used together with a wrist strap. The mat also acts as a
cushion to protect the small parts that are attached to printed
boards.
After removing a printed board or component, place it in the
antistatic bag or ESD safe packaging box.
