For transmitters rated at a maximum output power not listed above, the rec-
ommended separation distance d in meters (m) can be determined using the
equation applicable to the frequency of the transmitter, where P is the maxi-
mum output power rating of the transmitter in watts (W) according to the
transmitter manufacturer.
NOTE
At 80 MHz and 800 MHz, the separation distance for the higher frequency
range applies.
NOTE
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
An additional factor of 10/3 is used in calculating the recommended sepa-
ration 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.
