Do not press on the middle of the back cover or bend your NOOK. Doing so might
damage the screens.
4 Look around the edges of your
NOOK to see that the back cover is securely attached. If the
back cover is not securely attached, press edges together that did not seat correctly. If that does
not work, remove the back cover and repeat this procedure.
SIM Card
This section applies to the NOOK (Wi-Fi + 3G model) only.
The SIM card in your
NOOK (Wi-Fi + 3G model) is pre-installed. It is used when your NOOK
connects to the Barnes & Noble eBookstore and
NOOK data services over B&N Fast & Free
Wireless. You will never need to remove or change the SIM card. Specifically, please note the
following about the SIM card:
• You cannot use your
NOOK’s SIM card in a dierent mobile device, for example, a mobile
phone.
• You cannot use a dierent SIM card, for example, from a mobile phone, in your
NOOK.
• The SIM card in your
NOOK is associated with your NOOK, whether registered or not. Do not
swap SIM cards between
NOOKs. There is no reason to, and afterwards they will not be able to
connect to B&N Fast & Free Wireless.
Built-in Storage
Your NOOK has 2 GB of built-in flash memory. Of this, about 1.3 GB is available for storage of
your digital content. This is enough storage space for about 1500 eBooks or 300 periodical issues.
Periodicals tend to be larger because they have more graphical content.
The storage capacity for eBooks and other digital content will be aected by how many
personal files (for example, music files) you download onto your NOOK.
For information about how to add a supplemental microSD or microSDHC card, see “Adding
Storage” on page 154.
Battery
You do not install the battery. It is pre-installed and should last for years.
