26Recommended separation distances between portable and mobile RF communicationsequipment and the Alternating Control UnitThe system is intended for use in an electromagnetic environment in which radiated RF disturbances arecontrolled. The customer or the user of the system can help prevent electromagnetic interference by maintaining aminimum distance between portable and mobile RF communications equipment (transmitters) and the system asrecommended below, according to the maximum output power of the communications equipment.Rated maximumoutput power of transmitter(W)Separation distance according to frequency of transmitter (m)150 KHz to 80 MHz d =1.167√P80 MHz to 800 MHzd = 1.167√P800 MHz to 2.5 GHzd = 2.333√P0.01 0.117 0.117 0.2330.1 0.369 0.369 0.7381 1.167 1.167 2.33310 3.689 3.689 7.379100 11.667 11.667 23.333For transmitters rated at a maximum output power not listed above, the recommended separation distance d inmeters (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is themaximum 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 reflectionfrom structures, objects and people.recommended separation distances between portable and mobile RF communicationsequipment and the EQUIPMENT or SYSTEM – for ME EQUIPMENT or ME SYSTEM that are notLIFE-SUPPORTINGtechnical specifications
