Recommended Separation Distances between Portable and Mobile RF
Communications Equipment and the BIS VISTA Monitor
The BIS VISTA Monitoring System is intended for use in the electromagnetic environment
in which radiated RF disturbances are controlled. The customer or user of the BIS VISTA
system can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the BIS
VISTA system 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 meters (m) can be determined 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 ranges
applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects, and people.
