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.
