CAUTION: To avoid damaging the components and cards, handle them by
their edges, and avoid touching pins and contacts.
CAUTION: 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.
CAUTION: 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.
CAUTION: 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.
CAUTION: Press and eject any installed card from the media-card reader.
