The NIM Vital is intended for use in the electromagnetic environment specied below. The customer or the user of the NIM Vital should assure that it is used in such
an environment.

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 NIM Vital, including cables
specied by the manufacturer. Otherwise, degradation of
the performance of this equipment could result.

Portable and mobile RF communications equipment
should be used no closer to any part of the NIM Vital,
including cables, than the recommended separation
distance calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance
d = ( 6/E )√P
Where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer, E is the immunity test levels in volt per
meter (V/m), and d is the recommended separation
distance in meters (m).
Interference may occur in the vicinity of equipment
marked with the following symbol:
Note: These guidelines may not apply in all situations. Electromagnetic propagation is aected by absorption and reection from structures, objects and
people.
Recommended separation distances between portable and mobile RF communications equipment and the NIM Vital
The NIM Vital is intended for use in the electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the NIM Vital
can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters)
and the NIM Vital as recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be determined using the
equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the
transmitter manufacturer.
