Warning: 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.
Warning: RF mobile communications equipment can affect medical electrical equipment.
FORA IR20/IR21 is intended for use in an electromagnetic environment (for home healthcare and professional healthcare) in which radiated RF disturbances are
controlled. The customer or the user of FORA IR20/IR21 can help prevent electromagnetic interference by maintaining a minimum distance between the portable and
mobile RF communications equipment (transmitters) and FORA IR20/IR21 as recommended below, depending on 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 meters (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) depending on the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply to all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
