If the user of the device requires continued
operation during power mains interruptions,
it is recommended that the device 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.
NOTE:
UT is the a.c. mains voltage prior to application of the test level.
