Compatibility for Non-Life-Supporting Equipment
For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in meters (m) can be estimated using the equation applicable to the
frequency of the transmitter, where P is the maximum output power rate of the transmitter
in watts (W) according to the transmitter manufacturer.
