instructions that shipped with the product or at www.dell.com/regulatory_compliance.
POZOR Before touching anything inside your Embedded Box PC, ground yourself by touching an unpainted metal
surface, such as the metal at the back of the Embedded Box PC. While you work, periodically touch an unpainted metal
surface to dissipate static electricity, which could harm internal components.

connectors with locking tabs or thumb-screws that you must disengage before disconnecting the cable. When
disconnecting cables, keep them evenly aligned to avoid bending any connector pins. When connecting cables, ensure
that the ports and connectors are correctly oriented and aligned.
