Wireless Devices
Before boarding any aircraft or packing a wireless device in luggage that will be checked, remove the
batteries from the wireless device or turn the wireless device off (if it has an on/off switch). Wireless devices
can transmit radio frequency (RF) energy, much like a cellular telephone, whenever batteries are installed
and the wireless device is turned on (if it has an on/off switch).
Keyboard and Mouse Devices
Health Warning
Use of a keyboard or mouse may be linked to serious injuries or disorders.
When using a computer, as with many activities, you may experience occasional discomfort in your hands,
arms, shoulders, neck, or other parts of your body. However, if you experience symptoms such as persistent
or recurring discomfort, pain, throbbing, aching, tingling, numbness, burning sensation, or stiffness,
DO NOT IGNORE THESE WARNING SIGNS. PROMPTLY SEE A QUALIFIED HEALTH PROFESSIONAL,
even if symptoms occur when you are not working at your computer. Symptoms like these can be associated
with painful and sometimes permanently disabling injuries or disorders of the nerves, muscles, tendons, or
other parts of the body. These musculoskeletal disorders (MSDs) include carpal tunnel syndrome, tendonitis,
tenosynovitis, and other conditions.
While researchers are not yet able to answer many questions about MSDs, there is general agreement that
many factors may be linked to their occurrence, including: overall health, stress and how one copes with it,
medical and physical conditions, and how a person positions and uses his or her body during work and other
activities (including use of a keyboard or mouse). The amount of time a person performs an activity may also
be a factor.
