Caution About High Audio Volume
WARNING: Exposure to loud noise from any source for extended periods of time may aect your hearing. The
louder the volume, the faster your hearing may be aected. To protect your hearing:
• Limit the amount of time you use headsets or headphones at high volume.
• Avoid turning up the volume to block out noisy surroundings.
• Turn the volume down if you can’t hear people speaking near you. If you experience hearing
discomfort, including the sensation of pressure or fullness in your ears, ringing in your ears, or
mued speech, you should stop listening to the device through your headset or headphones
and have your hearing checked.
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 41-95 F 5-35 C
Operation 32-95 F 0-35 C
Storage 5-113 F -13-45 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.
