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.

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.

Where

is the maximum output power rating of
the transmitter in watts (W) according to the
transmitter manufacturer and

is the
recommended separation distance in metres

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:
Note 1
:
At 80 MHz and 800 MHz, 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.
* 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.
