ページを印刷する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.
