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 other countries. Information on your Kindle is on file with the FCC and can
