Manufacturer's guide and declaration – electromagnetic safety
This insufflator was designed to be used in the electromagnetic environment specified below. The user must ensure that it is in fact
used in this environment.

en 61000-4-3 80 Mhz at 2.5 ghz
note 1: at 80 Mhz and 800 Mhz, it is advisable to use the highest frequency band.
note 2: These recommendation may not be applicable in all situations. The propagation of electromagnetic waves is modified by
absorption and reflection due to structures, objects and people.
a The field strength of fixed transmitters, like base stations for radio telephones (mobile and fixed line) and mobile land radio
systems, amateur radio systems, AM/FM radio communication systems and TV systems cannot in theory be evaluated with accuracy.
To analyse the electromagnetic environment due to fixed RF transmitters, in situ measurements must be taken. if a field strength
measured in the environment in which this insufflator is used exceeds the applicable compliance levels shown above, check whether
this insufflator is functioning satisfactorily. if it is observed to be functioning abnormally, additional measures will have to be taken,
such as a change of direction or repositioning of the referencing system.
b Outside of the 150 khz to 80 Mhz frequency band, the field strength must be lower than 3 V/m.
Compliance electromagnetic environment - guide
level
Portable and mobile RF communication devices – cables included - must not
be used at a distance nearer than what is recommended. This distance is cal-
culated by applying the formula corresponding to the transmitter frequency.
Recommended separation distance
d = 1,16 √ P
3V d = 1,16 √ P 80 Mhz to 800 Mhz
d = 2,33 √ P 800 Mhz to 2.5 ghz
3V/m
Where is the maximum output power from the transmitter, in Watts
(W), assigned by the manufacturer of the transmitter and (d) is the recom-
mended separation distance in metres (m).
The field strengths emitted by fixed RF transmitters – which must be esta-
blished by in situ electromagnetic measurements – must be lower than the
compliance strength in each frequency band.
