13. EMC guidelines
•
Portable and mobile RF communications equipment can affect MEDICAL ELECTRICAL EQUIPMENT.
•
The OT600 should not be used adjacent to, or stacked with other equipment. If adjacent or stacked
use is necessary, the OT600 should be observed to verify normal operation in the configuration in
which it is used.
Guidance and manufacturer’s declaration - electromagnetic emmissions
The OT600 warming system is intended for use in the electromagnetic environment specified below. The customer or the user
of the OT600 should assure that it is used in such an environment.

RF emissions
CISPR 11
Group 1
The OT600 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 OT600 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 OT600 system.
The OT600 warming system is intended for use in the electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the OT600 system can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and the OT600 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.
Guidance and manufacturer’s declaration - electromagnetic immunity
The OT600 system is intended for use in the electromagnetic environment specified below. The customer or the user of the OT600
should assure that it is used in such an environment.
