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

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 where 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 anywhere you are
not allowed to use a mobile device.
Use Aeroplane Mode 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 crew member 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 harmful 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 your physician or the manufacturer to determine
whether they are adequately shielded from external RF signals.
Steps to Minimise 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 distance 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.
