Electromagnetic Immunity
Guidance and manufacturer’s declaration – electromagnetic immunity
The
cryo ICE BOX
is intended for use in the electromagnetic environment specified below. The customer or the
user of the
cryo ICE BOX
unit should assure that it is used in such an environment.

cryo ICE BOX
unit requires
continued operation during power

recommended that the
cryo ICE
BOX
unit be powered from an
uninterruptible power supply or a
battery.
