Electromagnetic Compatibility Guidance – Separation Distances
Recommended separation distances between portable and mobile RF communications equipment and the Model 825D
The Generator Model 825D is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the Generator Model 825D can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the Generator
Model 825D as recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (m) can
be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of
the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection
from structures, objects and people.
