Mains power quality should be that of a typical
commercial or hospital environment. If the user or
the KR-800A requires continued operation during
power mains interruptions, it is recommended
that the KR-800A be powered from an uninter-
ruptible power supply or battery.

Power frequency magnetic fields should be at
levels characteristic of a typical location in a typi-
cal commercial or hospital environment.
