Main power quality should be that
of a typical commercial and/or
hospital environment. If the user of
the Umana T1 requires continued
operation during power main
interruptions, it is recommended
that
the Umana T1 image
intensifier is powered from an
uninterruptible power supply or a
battery.

If image distortion occurs, it may
be necessary to position the
Umana T1 image intensifier
further from sources of power
frequency magnetic fields or to
install magnetic shielding. The
power frequency magnetic field
should be measured in the
intended installation location to
ensure that it is sufficiently low.
NOTE: U is the A/c main’s voltage prior to application of the test level.
The Umana T1 is suitable for use in a specified electromagnetic environment. Users should ensure that it is used in an
electromagnetic environment as described below:
