SPECIFICATION
Table 3: Guidance and Manufacturer’s Declaration - Electromagnetic Immunity
The MedicCO
2
LON device is intended for use within the electromagnetic environment specified below.
The customer or the operator of a MedicCO
2
LON Insufflator should ensure that it is used within such an
environment.

Guidance
Portable and mobile RF communications equipment
should be no closer to any part of the MedicCO2LON
device, including cables, than the recommended
separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended Separation Distance
Conducted RF 3 Vrms 3 Vrms d = 1.2 √ P
IEC 61000-4-6 150 kHz to
80 MHz
Radiated RF 3 V/m 3 V/m d = 1.2 √ P 80 MHz to 800 MHz
IEC 61000-4-3 80 MHz to
2.5 GHz
d = 2.3 √ P 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 meters (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 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 range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects, and/or 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
MedicCO
2
LON device is used exceeds the applicable RF compliance level above, the MedicCO
2
LON device
should be observed to verify normal operation. If abnormal performance is observed, additional measures
may be necessary, such as re-orienting or relocating the MedicCO
2
LON device.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
