Wireless Safety and Compliance

Turn Amazon Whispernet 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 Whispernet 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, many aviation agencies, including the
U.S. Federal Aviation Administration, require you to have permission from a crew member to
use your device's wireless service. If you have your wireless service turned off, you can use
your Kindle for reading once a crew member has said it is okay to use electronic devices.

Be Careful 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 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 harmful 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.

Exposure to Radio Frequency Energy

Your Kindle is designed and manufactured not to exceed the emission limits for exposure to
RF energy set by the Federal Communications Commission of the United States (FCC) and
regulating entities of the European Union and other countries. Information on your Kindle is
on file with the FCC and can be found under the Display Grant section of
