Instruction manual Operating table TruSystem 7000 – 1 730 263 – 11/2016
Table 4 according to IEC 60601-1-2:2007
Guidelines and manufacturer's declaration - electromagnetic immunity
The TruSystem 7000 operating table is intended for use in the environments as specified below. The customer or user of the
aforementioned device should ensure that it is operated in one of the environments as described.
Interference immunity
test IEC 60601 immunity Compliance level Electromagnetic environment - guidelines
Portable and mobile RF communications
equipment should not be used in the vicinity of
the TruSystem 7000 operating table, including
cables, nor not closer than the recommended
separation distance calculated from the
equation applicable to the frequency of the
transmitter.

P is the nominal rating of the transmitter in watts
(W) as per transmitter manufacturer data and d
is the recommended safe distance in
meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
a
should be less than the compliance level in
each frequency range.
b
Interference may occur in the
vicinity of equipment marked
with the following symbol:
Note 1 For 80 MHz and 800 MHz, the higher value applies.
Note 2 These guidelines might not be applicable in all cases. The propagation of electromagnetic
quantities is influenced by the absorption and reflection of buildings, items and human beings.
a 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. In order to determine the electromagnetic environment
with regard to stationary transmitters, a study of the location should be considered. If the measured
field strength in the location in which the aforementioned equipment is used exceeds the applicable
aforementioned compliance level, then the TruSystem 7000 operating table should be observed
to verify normal operation. Additional measures may be required such as e.g. reorienting or
relocating the TruSystem 7000 operating table.
b The field strength in the 150 kHz to 80 MHz frequency range should be less than 3 V/m.
