Magnetic Disturbance
☛
Never install the system where large ferrous masses (such as a column
in magnetic material) are placed at a distance of less than 2 m (6 feet)
from the magnet.
☛
Never install the system in the vicinity of lifts, underground trains, trams
or any other equipment that generates fluctuations of the magnetic field.
The magnetic field fluctuation must be contained within the limits
expressed in the next chapter, paragraph “Technical specifications”,
sub-paragraph “Installation area conditions”.
If necessary a fluctuation compensating device may be provided as an
option.
RF Disturbances
☛
Never install the system in the vicinity of devices where normal
operation of the latter involves frequent activation/shutdown, or in areas
where anomalous voltage fluctuations occur.
☛
The RF noise inside the room must be less, in the frequency range of
12.7 ÷ 13.3 MHz, than 30 dBµV/m. For this reason, turn off or move away
any RF sources operating in this frequency during examinations with
O-scan. In the case of particularly noisy areas, additional external
shielding may be required, to tolerate RF disturbances up to 60 dBµV/m.
☛
To assess susceptibility of the O-scan system to electromagnetic
disturbance deriving from peripheral equipment, the user interface
features a “Susceptibility test” protocol. See paragraph “Peripheral
equipment compatibility test”, chapters “Instructions for Safe Use” and
“System management”.

W a r n i n g
To avoid the appearance of artifacts on images, the O-scan system
must not be installed in areas subject to the presence of strong
magnetic disturbance, or in the vicinity of areas in which lifts, large
trucks or ambulances, trains, underground trains etc. operate.
W a r n i n g
Electrical equipment, even if compliant with the CISPR emission
requirements, may generate RF interference which may cause
artifacts on the image displayed on the O-scan system.
