Kangaroo™ Console | 48
Section VI: Additional Kangaroo Feeding Tube with IRIS Technology Information
Guidance and manufacturer’s declaration – electromagnetic immunity
The Kangaroo feeding tube with IRIS technology, when used with the console as a system is intended for use in the electromagnetic environment specified below. The customer or the user
should assure that it is used in such an environment.
Immunity test IEC 60601 test level Compliance level Electromagnet environment - guidance
Conducted RF
IEC 61000-4-6
Radiated RF

3 Vrms
150 kHz to 80 MHz

Portable and mobile RF communications equipment should be used no closer
to any part of the Kangaroo feeding tube with IRIS technology, when used with
the console as a system, including cables, than the recommended separation
distance calculated from the equation applicable to the frequency transmitter.
Recommended separation distance
d = [ 3.5 / V 1 ] √P
d = [ 3.5 / E 1 ] √P 80 MHz to 800 MHz
d = [ 7.0 / E 1] √P 800 MHz to 2.7 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
distances in meters (m).
Field strengths from fixed RF transmitters, as determined by an electronic site
survey,
a
should be less than the compliance level in each frequency range.
b
Interference may occur in the vicinity of equipment marked with the following
symbol:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency 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 Kangaroo feeding tube with IRIS technology, when used with the console as a system is used exceeds the applicable RF compliance level above, the
Kangaroo feeding tube with IRIS technology, when used with the console as a system should be observed to verify normal operation. If abnormal performance is observed, additional measures
may be necessary, such as reorienting or relocating the Kangaroo feeding tube with IRIS technology, when used with the console as a system.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
