WARNING: Disconnect all power sources before opening the tablet
cover or panels. After you finish working inside the tablet, replace all
covers, panels, and screws before connecting to the power source.
CAUTION: To avoid damaging the tablet, ensure that the work surface
is flat and clean.
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 tablet, ground
yourself by touching an unpainted metal surface. 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.
