Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.
Connect the equipment end of the strap to an unfinished chassis surface.
Place CF memory cards on an antistatic surface or in a static shielding bag. If the card is to be
returned to the factory, immediately place it in a static shielding bag.
Avoid contact between the card and clothing. The wrist strap protects the card from ESD voltages

Do not remove the wrist strap until the installation is complete.
