SPECIFICATIONS AND PERFORMANCE
Guidance and manufacturer's declaration - electromagnetic immunity
The 3D OCT-1 is intended for use in the electromagnetic environment specified below. The customer
or the user of the 3D OCT-1 should assure that it is used in such an environment.

Main power quality should be that of a
typical commercial or hospital environ-
ment. If the user or the 3D OCT-1
requires continued operation during
main power interruptions, it is recom-
mended that the 3D OCT-1 be powered
from an uninterruptible power supply or
battery.
