Interference with electronic equipment
Most modern electronic equipment is shielded from radio frequency signals. However, certain electronic equipment might not
be shielded against the radio frequency signals from the BlackBerry Universal Headset.
Pacemakers: Consult a physician or the manufacturer of your pacemaker if you have any questions regarding the effect of
radio frequency signals on your pacemaker. If you have a pacemaker, verify that you are using the headset in accordance with
the safety requirements associated with your particular pacemaker, which might include the following requirements:
• Always keep the headset more than 7.88 in. (20 cm) from the pacemaker when the headset is turned on.
• Do not carry the headset in your breast pocket.
• If you have any reason to suspect that interference is taking place, turn off the headset immediately.
Hearing aids: Some digital wireless devices may interfere with some hearing aids. In the event of such interference, consult
your wireless service provider or contact the manufacturer of your hearing aid to discuss alternatives.
Other medical devices: If you use any other personal medical device, consult the manufacturer of your device to determine if
the device is adequately shielded from external radio frequency energy. Your physician may be able to assist you in obtaining
this information.
Health care facilities: Turn off Bluetooth technology on the headset 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
radio frequency 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 the headset before boarding an aircraft. The effect of using Bluetooth
technology on the headset 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.
Dangerous areas
The BlackBerry Universal Headset 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 the headset 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.
