equipment should be used no closer to any
part of the device, including cables, than the
recommended separation distance calculated
from the equation applicable to the
frequency of the transmitter. Recommended
separation distance:
150k to 80 MHz
80 MHz to 80 0MHz
800 MHz to 2.7GHz
where P is the maximum output power rating
of the transmitter in watts (W) according to
the transmitter manufacturer and d is the
recommended separation distance in meters
(m).
