Supported Cards
Following are the specifications of supported cards:
 A microSD or microSDHC card with a storage capacity of up to 32 GB. For simplicity's
sake, we refer to these both as microSD cards below.
Class 2, 4, and 6 microSD cards are supported. Class 6 is faster than class 4, which is faster

than class 2. The class should be mentioned on the packaging for the microSD card and
printed on the card itself. If no speed is indicated, the card is a class 2 card. The speed of
the card does not affect page display speeds. It can affect read and write speeds when
transferring eBooks and personal files to and from the SD card.
Approximate Storage Capacities
Supplemental microSD and microSDHC cards will hold about 750 eBooks per gigabyte or 300
ePeriodicals per gigabyte.
Inserting a microSD Card
To insert a microSD card:
1 Press the power button for 5-9 seconds to turn off your nook.
2 Remove the back cover.
3 Place your nook on a flat surface with the open back facing up and the top away from you.
4 The microSD card holder has a little metal cover. A rounded, cut-out area below the cover
allows you to insert a finger nail. With your finger nail, lift up on the bottom edge of the
metal cover, until the cover points straight up. In the space for the microSD card, you see
eight contacts toward the top of the holder (near the hinge).
5 With the contacts on the microSD card facing down and lined up with the contacts in the
holder (the thicker base toward you and the notch to the right), drop the microSD card
into place. You might need to move it around a bit. It should fit snuggly.
6 With a finger, close the metal cover until it lies flat and you feel a click.
If the cover does not close easily, do not force it. Doing so will damage the microSD
card holder. Instead, ensure that the microSD card is correctly positioned (contacts
facing down and the notch to the right and flat and snug in the holder), and then try
again.
