Electrostatic discharge
CAUTION: Some parts are sensitive to electrostatic discharge (ESD). Look for the ESD
reminder when removing product parts. Always perform service work at an ESD-protected
workstation or mat, or use an ESD strap. If an ESD workstation, mat, or strap is not available, ground
yourself by touching the sheet-metal chassis before touching an ESD-sensitive part.
Protect the ESD-sensitive parts by placing them in ESD pouches when they are out of the product.
