Guidance and manufacturer’s declaration – electromagnetic immunity
The STIMPOD NMS410/NMS450X is intended for use in the electromagnetic environment specified below. The customer or the user of the STIMPOD NMS 410/450X should assure that
it is used in such an environment.

Portable and mobile RF communications equipment should be used no closer to any
part of the STIMPOD NMS 410/450X, including cables, than the recommended separation
distance calculated from the equation applicable to the frequency of the transmitter.
Recommended separation distance
d = 1,2
80 MHz to 800 MHz
d = 2,3
800 MHz to 2,5 GHz
where P is the maximum output power rating of the transmitter in watts (W) according
to the transmitter manufacturer and d is the recommended separation distance in metres
(m).
Field strengths from fixed RF transmitters, as determined by an electromagnetic site
survey,
a
should be less than the compliance level in each frequency range.
Interference may occur in the vicinity of equipment marked with the
following symbol:
NOTE 1
At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast
cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the
measured field strength in the location in which the STIMPOD NMS 410/450X is used exceeds the applicable RF compliance level above, the STIMPOD NMS 410/450X should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the STIMPOD NMS 410/450X.
