Safety Warnings

• Handle components by only their handles or edges; do not touch the printed circuit boards or connectors.

• Place a removed component board side up on an antistatic surface or in a static-shielding container. If

you plan to return the component to the factory, immediately place it in a static-shielding container.

• Avoid contact between the printed circuit boards and clothing. The wrist strap only protects components

from ESD voltages on the body; ESD voltages on clothing can still cause damage.

• Never attempt to remove the printed circuit board from the metal carrier.

For the safety of your equipment, periodically check the resistance value of the antistatic wrist strap. Maintain

the value between 1 and 10 Mohm.
