Other Safety Considerations
Engaging in repetitive motions such as pressing keys or playing some games may cause
you to experience occasional discomfort in your hands, arms, shoulders, neck, or other
parts of your body. Discontinue use of your device and consult a physician if you experience
discomfort. To reduce risk of these symptoms avoid prolonged use and take frequent breaks.
Small parts contained in your device and its accessories may present a choking hazard to
small children.
Using your Kindle while operating a vehicle is not recommended and may be prohibited or
restricted in some areas. If you are in an area where using your Kindle while operating a
vehicle is allowed, always give full attention to the operation of the vehicle and stop using
your Kindle if it becomes a distraction.
Wireless Safety and Compliance
Turn your wireless connection off in areas where wireless use is forbidden or when it may
cause interference or danger. Some specific situations are described below. In general, you
should not use your Kindle with your wireless connection turned on any place you are not
allowed to use a cellular device.
Turn Off Wireless When Flying
To prevent possible interference with aircraft systems, the U.S. Federal Aviation Administration
regulations and many other aviation agencies require you to have permission from a
crewmember to use your device’s wireless service.
Using Your Kindle Around Other Electronic Devices
Kindle generates, uses, and can radiate radio frequency (RF) energy and, if not used in
accordance with its instructions, may cause interference to radio communications and
electronic equipment. External RF signals may affect improperly installed or inadequately
shielded electronic operating systems, entertainment systems, and personal medical devices.
While most modern electronic equipment is shielded from external RF signals, if in doubt,
check with the manufacturer. For personal medical devices (such as pacemakers and hearing
aids), consult with your physician or the manufacturer to determine if they are adequately
shielded from external RF signals.
Steps to Minimize Interference
If your Kindle does cause interference to radio or television reception (which you can
determine by turning your Kindle off and on), you can try to correct the interference by one
or more of the following measures: reorient or relocate the receiving antenna for the radio or
television; increase the separation between the radio or television and your Kindle; connect
equipment and receivers to different outlets; or consult the radio or television manufacturer
or an experienced radio/TV technician for help.
Watch for Signs
There are some places where RF signals could constitute a hazard, such as health care
facilities, and construction sites. If you are not sure, look around for signs indicating that
two-way radios or cell phones should be turned off.
