Table 4
Recommended separation distances between portable and mobile RF communications equipment and the Veroval
The Veroval BPU 22 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer
®
or the user of the Veroval BPU 22 can help prevent electromagnetic interference by maintaining a minimum distance between portable and
®
mobile RF communications equipment (transmitters) and the Veroval
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.
