13 EMC COMPATIBILITY STATEMENT
EMC Guidelines for the Operatherm OP3 system
•
Portable and mobile RF communications equipment can affect MEDICAL ELECTRICAL
EQUIPMENT.
•
The KANMED Operatherm OP3 system should not be used adjacent to, or stacked with other
equipment. If adjacent or stacked use is necessary, the KANMED Operatherm OP3 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 Operatherm OP3 system is intended for use in the electromagnetic environment specified
below. The customer or the user of the KANMED Operatherm OP3 should assure that it is used in such an
environment.

Group 1
KANMED Operatherm OP3 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 Operatherm OP3 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 Operatherm OP3
system.
The KANMED Operatherm OP3 system is intended for use in the electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the KANMED Operatherm OP3 system
can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the KANMED Operatherm OP3 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.
