Oxygen ConcentratorPN 14940837 B — 10Recommended separation distancesbetween portable and mobile RF communications equipment and the Companion 5The Companion 5 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.The customer or the user of the Companion 5 can help prevent electromagnetic interference by maintaining a minimumdistance between portable and mobile RF communications equipment (transmitters) and the Companion 5 as recommendedbelow, according to the maximum output power of the communications equipment.Rated maximumoutput power oftransmitterWSeparation distance according to frequency of transmitterm150 kHz to 80 MHz 80 MHz to 800 MHz 800 MHz to 2,5 GHz0,01 0.12 0.12 0.230,1 0.38 0.38 0.731 1.2 1.2 2.310 3.8 3.8 7.3100 12 12 23For 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 powerrating 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 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflectionfrom structures, objects and people.d = 1.2 P d = 1.2 P d = 2.3 P
