hospital environment.
Mains power quality
should be that of a
typical commercial or
hospital environment.
Mains power quality
should be that of a
typical commercial or
hospital environment. If
the user of the MicroCO
requires continued
operation during power
mains interruptions, it is
recommended that the
MicroCO be powered
from an uninterruptable
power supply or a
battery.
If incorrect operation
occurs, it may be
necessary to position
the MicroCO further
from sources of power
frequency magnetic
fields or to install
magnetic shielding. The
power frequency
magnetic field should be
measured in the
intended installation
location to assure that it
is sufficiently low.
