portable and mobile RF communications equipment and the Syramed µSP6000 Series
The Syramed µSP6000 Series is intended for use in the electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the Syramed µSP6000 Series can help prevent electromagnetic interference by maintaining a miminum
distance between portable and mobile RF communications equipment (transmitters) and the Syramed µSP6000 Series as recommended
below, according to the maximum output power of the communication equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (m) can be
determined using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter
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 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.
NOTE 3 An additional factor of 10/3 is used in calculating the recommended separation distance for transmitters in the ISM frequency
bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2.5 GHz to decrease the likelihood that mobile/portable
communications equipment could cause interference if it is inadvertently brought into patient areas.
NOTE 4 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
