Temperature Ranges

Your NOOK should function as designed in these temperature ranges:

Use

Fahrenheit

Celsius

Charging

41– 95 ºF

5 – 35 ºC

Operation

32 – 104 ºF

0 – 40 ºC

Storage

5 – 113 ºF

-15 – 45 ºC

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” on page 22.

Water and Weather

Your NOOK has a degree of water resistance, for example, to a misty fog. (We do want San Francisco residents to buy NOOKs.) If your NOOK gets damp, just dry the surface with a clean, dry cloth before you put it away. But don’t let your NOOK get too wet. It is not water proof. If it does get wet, let it dry completely before using it.

Reading Screen

You do not need to touch the reading screen, and should try to not do so. Fingerprints can permanently damage the reading screen if they are not removed. If the screen gets fingerprints, grime, dust, or water on it (or for that matter, red wine, spaghetti sauce, or mustard), you should clean it with a damp soft cloth (for example, a micro-fiber cloth). Do not use any chemicals to clean the reading screen.

The reading screen has a scratch-resistant coating, but it is possible to scratch the screen, so you should clean it carefully. Keeping the screen clean in the first place is a better strategy than cleaning it. You should clean it infrequently, not often.

Color Touchscreen

The color touchscreen is meant for touching, but you should also clean it. You might clean it after several days of use, or if you notice the screen needs cleaning. Clean the touchscreen with a damp soft cloth (for example, a micro-fiber cloth). Do not use any chemicals to clean the touchscreen.
