Transmitter in Watts
For transmitters rated at a maximum output power not listed above, estimate
the separation distance (d) using the equation in the corresponding column,
where P is the maximum output [power rating of the transmitter in watts (W)]
according to the transmitter manufacturer.

Note:
Portable and mobile RF communications equipment can affect medical electrical
equipment. Such RF equipment should be used no closer to any part of the monitoring
system, including cables, than the recommended separation distance calculated from
the equation appropriate for the frequency of the transmitter.
