Table 12.8 – Recommended separation distances between portable and mobile RF
communications equipment and the VERITAS Vision System
Recommended separation distances between portable and mobile RF communications
equipment and the VERITAS Vision System
The VERITAS Vision System is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the VERITAS Vision System can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the VERITAS Vision 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 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.
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 affected by absorption
and reflection from structures, objects, and people.
