Electromagnetic compatibility (EMC) immunity guidelines and declarations for GeoScan
systems
GeoScan systems are intended for use in the electromagnetic environment specified
below. The customer or user of a GeoScan system should ensure that it is used in such an
environment.

of the GeoScan system requires
continued operation during
power mains interruptions, it is
recommended that the GeoScan
be powered from an
uninterruptible power supply or
a battery.
