Mains power quality should be
that of a typical commercial or
hospital environment. If the user
of the F Series Fetal & maternal
Monitor requires continued
operation during power mains
interruptions, it is recommended
that the F Series Fetal &
maternal Monitor be powered
from an uninterruptible power
supply or a battery.
NOTE: U
T
is the a.c. mains voltage prior to application of the test level.
