Guidance and manufacturer's declaration – electromagnetic immunity –
The KARL STORZ NBU module 408100 20 is intended for use in the electromagnetic environment specified below.
The customer or user of the KARL STORZ NBU module 408100 20 should ensure that it is used in such an environment.
Immunity test
EN/IEC 60601 test level
Conducted RF
3 V
rms
IEC 61000-4-6
150 kHz to 80 MHz
Radiated RF
3 V/m
IEC 61000-4-3
80 MHz to 2.5 GHz
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 by 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 unit is used exceeds the applicable RF
compliance level above, the unit should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary,
such as reorienting or relocating the unit.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.

for equipment and systems that are not life-supporting
Compliance level
Portable and mobile RF communications equipment should be used
no closer to any part of the KARL STORZ NBU module 408100 20,
including cables, than the recommended separation distance
calculated from the equation applicable to the frequency of the
transmitter.
Recommended separation distance:
B
3 V
rms
B
3 V/m
E
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 in meters [m].
