Table 206. Recommended separation distances between portable and mobile RF communications equipment and DSK-1031
DSK-1031 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of DSK-1031 can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and DSK-1031 as recom-
mended 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 ap-
plicable 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.

At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
These guidelines may not apply in all situations. Electromagnetic propagation is aff ected by absorption and refl ection from
structures, objects and people.
