For transmitters rated at a maximum output power not listed above, the recommended separation distance d in
meters (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 40.70 MHz.
NOTE 3: An additional factor of 10/3 has been incorporated into the formulae 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.
