Mains power quality
should be that of a
typical commercial or
hospital environment.
If the user of the device
requires continued
operation during power
mains interruptions, it is
recommended that the
device 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
