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

IEC 61000-4-8 3 A/m 3 A/m Power frequency magnetic field
should be at levels characteristic of a
typical location in a typical
commercial or hospital environment.
