For transmitters rated at a power not listed above, the DISTANCE can be estimated using the
equation in the corresponding column, where P is the power rating of the transmitter in watts
(W) according to the transmitter manufacturer.
NOTE: These are guidelines. Actual conditions may vary.
2.4 Limitations Management
Adhering to the distance separation recommended in Table 3-4, between 150 KHz & 2.5 GHz,
will reduce disturbances recorded at the image level, but may not eliminate all disturbances.
