14 EMC COMPATIBILITY STATEMENT
EMC Guidelines for the BabyWarmer BW3 system
•
Portable and mobile RF communications equipment can affect MEDICAL ELECTRICAL EQUIPMENT.
•
The Kanmed BabyWarmer BW3 system should not be used adjacent to, or stacked with other equipment. If
adjacent or stacked use is necessary, the Kanmed BabyWarmer BW3 system
should be observed to verify normal
operation in the configuration in which it is used.
Guidance and manufacturer’s declaration
- electromagnetic emissions
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 should assure that it is used in such an environment.

RF emissions
CISPR 11
Group 1
Kanmed BabyWarmer BW3 system uses RF energy only for its internal
function. Therefore, its RF emissions are very low and are not likely to
cause any interference in nearby electronic equipment.

The Kanmed BabyWarmer BW3 system is suitable for use in all
establishments, including domestic establishments and those directly
connected to the public low-voltage power supply network that
supplies buildings used for domestic purposes.

Recommended separation distances between portable and mobile RF communications equipment and the Kanmed
BabyWarmer BW3
system.
The Kanmed BabyWarmer BW3 system is intended for use in the electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the Kanmed BabyWarmer BW3 system can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the Kanmed
BabyWarmer BW3 system as recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (m) can
be established using the equation applicable to the frequency of the transmitter, where
P
is the maximum output power rating in
watts (W) according to the transmitter manufacturer.
Note 1
: At 80 MHz and 800 MHz, the separation distance for 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 people.
