be used no closer to any part of the
MicroLoop, including any cables, than
the recommended separation

If incorrect operation
occurs, it may be
necessary to position the
MicroLoop further from
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.
