a. These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structure, objects and people.
b. The compliance levels in ISM bands (parts of the tested bandwidth) are intended to decrease the
likelihood that mobile/portable communications equipment could cause interference if it is
inadvertently brought into patient areas. For this reason a safety factor of 10/3 is used in calculating
the recommended separation distance for transmitters in these frequency ranges.
c. 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 asses 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 FLOW-i is used exceeds the applicable RF compliance level above, the
FLOW-i should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as relocating the FLOW-i.
d. The ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6,765 MHz to
6,795 MHz; 13,553 MHz to 13,567 MHz; 26,957 to 27,283 MHz; and 40,66 MHz to 40,70 MHz.
e. At 80 MHz and 800 MHz, the higher frequency range applies.
WARNING! The FLOW-i anesthesia system should not be used adjacent to or stacked with
other equipment. If such a configuration is necessary, the FLOW-i anesthesia system should
be observed to verify normal operation during use.
