Guidance and manufacturer's declaration - electromagnetic immunity
The KANMED Operatherm OP3 system is intended for use in the electromagnetic environment specified below. The customer
or the user of the KANMED Operatherm OP3 system should assure that it is used in such an environment.
Immunity test IEC 60601 test level
Conducted RF 3 Vrms
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.
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
Note 2:
reflection from structures, objects and people.
* 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
access 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 KANMED Operatherm OP3 system is used exceeds the applicable RF
compliance level above, the KANMED Operatherm OP3 system should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the Operatherm OP3.
** Over the frequency range of 150 kHz to 80 MHz, field strength should be less than 3 V/m.
Compliance
Electromagnetic environment - guidance
level
Portable and mobile RF communications equipment
should be used no closer to any part of the KANMED
Operatherm OP3 system, including cables, than the
recommended separation distance calculated from the
equation applicable to the frequency of the transmitter.
Recommended separation distance
d = 1,17 √ P
3 Vrms d = 1,17 √ P
d = 2,33 √ P
Where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
3 V/m manufacturer and d is the recommended separation
distance in metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey*, should
be less than the compliance level in each frequency
range**
Interference may occur in the vicinity of equipment
