Take note of the following when working with Cardbus/PC cards:

with a flat screwdriver.
2. Remove the metal cover from the guide rail.
3. Insert the PCMCIA card or Cardbus card you require.
!
Caution
Make sure that the eject button for Cardbus/PC cards is fully depressed before
inserting the PC card. If this is not the case, a card may jam in the slot when
inserting thin PC cards (flash memory cards, for example). The PC card can then
not be inserted properly.
The nameplate of the PC card must be visible to the rear of the device on being
inserted.
Do not remove the cared until data transfer has stopped (danger of loss of data
and system crash).
