Memory Flash Cards are inserted and ejected in much the same way as 
diskettes.
To insert a Flash Memory card, align the card with the socket and slide 
the card into the socket until it locks into place. Note that some Flash 
Memory cards must be prepared by your operating system before you can 
use them for data storage. See your Flash Memory card manual for 
details.
To eject a Flash Memory card, first ensure that the panel PC is not access-
ing the memory card or device. Then press the appropriate eject button on 
the socket. When the card pops out of the socket, remove it and store it 
properly.
