Electromagnetic Immunity
The Medela Vario 18 AC/DC c/i are intended for use in the electromagnetic environment spe-
cified below. The customer or the user of the Medela Vario 18 AC/DC c/i should assure that
they are used in such environment.
Immunity IEC 60601
Tests test level
Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to 80
MHz
Radiated RF

IEC 61000-4
80 MHz to 2.5

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 ab-
sorption and reflection from structures, objects and people.
a
Field strengths from fixed RF 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
Medela Vario 18 AC/DC c/i are used exceeds the applicable RF compliance level above, the Medela Vario
18 AC/DC c/i should be observed to verify normal operation. If abnormal operation is observed, additional
measures may be necessary, such as reorienting or relocating the Medela Vario 18 AC/DC c/i .
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Compliance Electromagnetic
level environment - guidance
Portable and mobile RF communications
equipment should be used no closer to
any part of the Medela Vario 18 AC/DC c/i,
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of the
transmitter.
3 Vrms Recommended separation distance
d = 1.2 √ P
d = 1.2 √ P
80 MHz to 800 MHz
3 V/m d = 2.3 √ P
800 MHz to 2.5 GHz
where P is the maximum output power ra-
ting of the transmitter in watts (W) accor-
ding to the transmitter manufacturer and d
is the recommended separation distance in
meters (m)
Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
surveya, should be less than the compli-
ance level in each frequency range.
Interference may occur in the vicinity of equip-
ment marked with the following symbol:
