Health care facilities: Turn off all wireless connections on the BlackBerry device in health care facilities when
any regulations posted in these areas instruct you to do so. Hospitals or health care facilities might be using
equipment that could be sensitive to external RF energy.
Aircraft: Federal Aviation Administration (FAA) and Federal Communications Commission (FCC) regulations
prohibit using the radio of wireless devices while in the air. Turn off all wireless connections on the BlackBerry
device before boarding an aircraft. The effect of using the BlackBerry device with wireless connections turned
on in an aircraft is unknown. Such use might affect aircraft instrumentation, communication, and performance,
might disrupt the network, might otherwise be dangerous to the operation of the aircraft, and might be illegal.
With all wireless connections on the BlackBerry device turned off, use only non-radio based device applications
in accordance with airline regulations for electronic devices.
Dangerous areas
The BlackBerry® device is not an intrinsically safe device and is not suitable for use in hazardous environments,
where such devices are required, including without limitation, in presence of gas fumes, explosive dust situations,
operation of nuclear facilities, aircraft navigation or communication services, air traffic control, and life support
or weapons systems.
Potentially explosive atmospheres: Turn off all wireless connections on the BlackBerry device when in any
area with a potentially explosive atmosphere, and obey all signs and instructions. Sparks in such areas could
cause an explosion or fire resulting in bodily injury or even death.
Areas with a potentially explosive atmosphere are often, but not always, clearly marked. They include fueling
areas such as gasoline or petrol stations; below deck on boats; fuel or chemical transfer or storage facilities;
vehicles using liquefied petroleum gas (such as propane or butane); areas where the air contains chemicals or
particles, such as grain, dust, or metal powders; and any other area where you would normally be advised to turn
off your vehicle engine.
Do not use the phone on the BlackBerry device to report a gas leak in the vicinity of the leak. Leave the area and,
if the phone is available and active on the BlackBerry device, make the call from a safe location.
Blasting areas: To avoid interfering with blasting operations, turn off all wireless connections on the
BlackBerry device when in a "blasting area" or in areas posted: "Turn off two-way radio." Obey all signs and
instructions.
