Note:
Portable and mobile communications equipment should be separated from the system by no less
than the distances calculated or listed in Table 9 on page 27.
Warning: Portable RF communications equipment (including peripherals
such as antenna cables and external antennas) should be used no closer
than 30 cm (12 inches) to any part of the MODEL OR TYPE REFERENCE
of the ME EQUIPMENT or ME SYSTEM, including cables specified by the
manufacturer. Otherwise, degradation of the performance of this equipment
could result.

Group 1
Class A Nexus DR uses RF energy only for its internal function;
therefore, its RF emissions are very low and unlikely to cause
any interference in nearby electronic equipment.
Harmonics IEC

Class A
Flicker IEC 61000-3-3 Dmax = 4 %
Nexus DR is suitable for use in all establishments other
than domestic and those directly connected to public low-
voltage power supply network that supplies buildings used for
domestic purposes.
