Mains power quality
should be that of a
typical commercial or
hospital environment.
If the user of the
Precision Montage
MRI System requires
continued operation
during power mains
interruptions, it
is recommended
that the Precision
Montage MRI
System be
powered from an
uninterruptible power
supply or a battery.
Power frequency
magnetic fields
should be at levels
characteristic of a
typical location in a
typical commercial or
hospital environment.
Magnetic fields from
common appliances
are not expected to
affect the device.
