Headphone Safety

Listening to audio at high volume for extended periods of time can cause hearing
damage. To avoid this problem, consider the tips below:
1. Keep the volume down
2. Avoid prolonged, continuous listening; and
3. Wear headphones that isolate the wanted audio from background noise.

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, the U.S. Federal Aviation
Administration regulations 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
