- Microdrive

Inserting a memory card
- Open the memory card door.

- Insert a memory card.
Before inserting the memory card, read the following information:
- If you are inserting a SmartMedia card, make sure the gold contact area faces up.
- If you are using a Memory Stick Duo, a Memory Stick PRO Duo, or a Mini SD, be sure to connect it to the adapter that came with the card before inserting it into the slot.
- If you are inserting a CompactFlash Type I or Type II, Microdrive, Memory Stick, xD, or Secure Digital card, make sure the name label faces up.
- If your card has an arrow mark, make sure the arrow points toward the All-In-One.
- Insert only one digital camera memory card at a time because the All-In-One recognizes only one source for photos at a time.
