Guidance and manufacturer's declaration – electromagnetic immunity
The Elekta Neuromag
®
system is intended for use in electromagnetic environmen specified below. The
customer or the user of the Elekta Neuromag
®
system should assure that it is used in such an environment.

Mains power quality should be that of a
typical commercial or hospital
environment. The system is equipped
with no-voltage mains release switch;
after mains interruption a normal power-
up sequence by the operator is
necessary. If the user of the Elekta
Neuromag
®
system requires continued
operation during power mains
interruptions, it is recommended that the
Elekta Neuromag
®
system be powered
from an uninterruptible power supply.

Not applicable
Not applicable
The system is intended to measure
magnetic fields at a very low level in a
frequency range that includes 50/60 Hz.
A magnetic site survey and adjacent
determination of necessary magnetic
shielding must be performed for each
installation site prior to installation as a
normal part of the site planning.
