Guidance and manufacturer's declaration - electromagnetic immunity
The Syramed µSP6000 Series is intended for use in the electromagnetic environment specified below. The customer or the user of the
Syramed µSP6000 Series should assure that it is used in such an environment.

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.
a
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 MHz to 27.283 MHz; and 40.66 MHz to 40.7 MHz.
b
The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2.5 GHz
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, an additional 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 assess 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 Syramed µSP6000 Series is used exceeds the applicable RF compliance level above, the
Syramed µSP6000 Series should be observed to verify normal operation. If abnormal performance is observed, additional measures
may be necessary, such as reorienting or relocating the Syramed µSP6000 Series.
d
Over the frequency range 150 kHz to 80 MHz, field strength should be less than 10 V/m.

Electromagnetic environment - guidance
Portable and mobile RF communications equipment should not be used
no closer to any part of the Syramed µSP6000 Series, including cables,
than the recommended separation distance caculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance
d = 0.35√P
d = 1.2√P
d = 1.2√P 80 MHz to 800 MHz
d = 2.3√P 800 MHz to 2.5 GHz
where P is the maximum output power rating of the transmitter in watts
(W) according to the transmitter manufacturer and d is the recommended
separation distance in meters (m).
