Removing Memory Cards Warning: When removing or installing a memory card, do not touch its gold connectors. Handle the card only by the edges. 1. To remove a memory card, locate the brackets that secure the card on both sides. Carefully spread the brackets apart until the card releases on each side (Figure 6). The card can then be pulled up and out. Note: If there is a memory card in the upper memory slot (Figure 6B), it must be removed before removing a card in the lower slot (Figure 6A).
