Guidance and manufacturer's declaration - electromagnetic immunity
The Kanmed BabyWarmer BW3 system is intended for use in the electromagnetic environment specified below. The customer or the user of the
Kanmed BabyWarmer BW3 system should assure that it is used in such an environment.

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 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
BabyWarmer BW3 system is used exceeds the applicable RF compliance level above, the Kanmed BabyWarmer BW3 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.

Electromagnetic environment - guidance
Portable and mobile RF communications equipment should be
used no closer to any part of the Kanmed BabyWarmer BW3
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
d = 1,17 √ P
80 MHz to 800 MHz
d = 2,33 √ 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 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 marked with
the following symbol:
at least 30%
Mains power quality should
