N-595
Table 14: Electromagnetic Immunity
The N-595 is suitable for use in the specified electromagnetic environment. The
customer and/or user of the N-595 should assure that it is used in an electromagnetic
environment as described below.

Guidance
Mains power quality
should be that of a typical
commercial and/or
hospital environment. If
the user of the N-595
requires continued
operation during power
mains interruption, it is
recommended that the
N-595 be powered from an
uninterruptible power
supply or battery.

If image distortion occurs,
it may be necessary to
position the N-595 further
from the 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.
