Technical Specifi cations
Medical electrical equipment needs special precautions regarding EMC and needs to be installed
according to the EMC information provided. Careful consideration of this information is essential when
stacking or collocating equipment and when routing cables and accessories.
RF mobile communications equipment can effect medical electrical equipment.
Recommended separation distances between portable and
mobile RF communications equipment and the ProCair Plus
control unit
The ProCair Plus control unit is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the ProCair Plus control unit can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the ProCair Plus control unit as recommended below, according
to the maximum output power of the communications equipment.
For transmitters rated at a maximum output power not listed above, the recommended separation distance d
in metres (m) can be estimated 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.
NOTE1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
refl ection from structures, objects and people.
