Mains power quality should be that
of a typical commercial or hospital
environment. If the user of Basic 30
requires continued operation during
power mains interruptions, it is recom-
mended that Basic 30 be powered
from an uninterruptible power supply
or a battery.
Power frequency magnetic fields
should be at levels of a typical com-
mercial or hospital environment.
