Caring for Your NOOK
To take the best possible care of your NOOK, please follow the recommendations below.

Temperature Ranges

Your NOOK should function as designed in these temperature ranges:
Use Fahrenheit Celsius
Chargin 41-950 F 5-350 C
Operation 32-950 F 0-350 C
Storage 5-1130 F -13-450 C
Outside of these ranges, your NOOK might develop power, display, and/or software issues. If temperatures are
extremely cold or hot, permanent physical damage can result. Such damage is not covered by the warranty. Storage
applies to temporary locations like the trunk of your car (or other motor vehicle) as well as long-term storage.
Even on a day that is not very hot, the passenger compartment or trunk of a car can be extremely hot. Do not leave
your NOOK in a car.
High storage temperatures reduce battery life. For more information, see “Charging Recommendations”.

Caring for the Touchscreen

You should clean the touchscreen on your NOOK from time to time. Clean the screen with a damp soft cloth, such
as a micro-fiber cloth. Micro-fibre cloths are available from Barnes & Noble stores and from partner retailers. Do not
use any chemicals to clean the screen.
