Compliance
The NVM5 System uses RF energy only for its internal
function. Therefore, its RF emissions are very low and are
Group 1
not likely to cause any interference in nearby electronic
equipment.
The NVM5 System is suitable for use in all establishments,
Class A
including domestic establishments and those directly
connected to the public low-voltage power supply network that
Class A
supplies buildings used for domestic purposes.

If image distortion occurs, it may
be necessary to position the NVM5
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.
