Instrucciones de seguridad
Utilice las siguientes directrices de seguridad para proteger su equipo de posibles daños y para garantizar su seguridad personal.
NOTA: Before working inside your computer, read the safety information that shipped with your computer. For more
safety best practices, see the Regulatory Compliance home page at www.dell.com/regulatory_compliance.
NOTA: Disconnect all power sources before opening the computer cover or panels. After you finish working inside the
computer, replace all covers, panels, and screws before connecting to the electrical outlet.
PRECAUCIÓN: To avoid damaging the computer, ensure that the work surface is flat and clean.
PRECAUCIÓN: To avoid damaging the components and cards, handle them by their edges, and avoid touching pins and
contacts.
PRECAUCIÓN: You should only perform troubleshooting and repairs as authorized or directed by the Dell technical
assistance team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. See the safety
instructions that shipped with the product or at www.dell.com/regulatory_compliance.
PRECAUCIÓN: Before touching anything inside your computer, ground yourself by touching an unpainted metal surface,
such as the metal at the back of the computer. While you work, periodically touch an unpainted metal surface to dissipate
static electricity, which could harm internal components.
PRECAUCIÓN: When you disconnect a cable, pull on its connector or on its pull tab, not on the cable itself. Some cables
have 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.
PRECAUCIÓN: Press and eject any installed card from the media-card reader.
