Mains power quality
should be that of a typical
commercial or hospital
environment. If the user of
the FC-700 system requires
continued operation
during power mains
interruptions, it is
recommended that the
FC-700 system be
powered from an
uninterruptible power
supply or a battery
Note: Uт is the a.c. mains voltage prior to application of the test level.
The FC-700 system is intended for use in the electromagnetic environment specified
below.
The customer or the user of the FC-700 system should assure that it is used in such an
environment
