Mains power quality should be
that of a typical commercial or
hospital environment. If the user
of SDC3 requires continued
operation during power mains
interruptions, it is recommended
that SDC3 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.
