<5 % UT a typical commercial or hospital
(>95 % dip in UT) environment. If the user of the Model
for 0.5 cycle 004 Image Intensifier requires
continued operation during power
40 % UT mains interruptions, it is
(60 % dip in UT) recommended that the Model 004
for 5 cycles Image Intensifier be powered from an
uninterruptible power supply or a
70 % UT battery.

If image distortion occurs, it may be
0,3 A/m
necessary to position the Model 004
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 assure that it is
sufficiently low.
