Inserting and Removing a Memory Card 
When inserting cards, the memory card should be inserted with the card label in the same direction as the LED 
power light. Also, make sure that a card's indented tracks line up with the side rails in the Compact Flash slot. 
Insert the card carefully and firmly until it is fully seated in the slot. 
To remove the card, pull out the card carefully.
