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 may 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.
Co-channel mobile satellite systems: To reduce the potential for harmful interference with
co-channel mobile satellite systems, the BlackBerry device operates in the 5150 to 5250 MHz
band only when associated with a wireless access point indoors.
CAUTION: High-power radar systems are allocated as primary users (meaning they have
priority) of the 5250 to 5350 MHz and 5650 to 5850 MHz bands. These radar systems might
cause interference with or damage to the BlackBerry device.
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.
