Recommended separation distances between portable and mobile RF
communications equipment and the TRAUS SUS20
The PIEZOART is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the PIEZOART can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the PIEZOART as recommended
below, according to the maximum output power of the communications equipment
Rated maximum output
Power of transmitter
(W)
For transmitters rated at a maximum output power not listed above, the recommended separation distance ‘d’ in meters (m) can
be estimated by 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 higher frequency range applies.
Note 2: These specifications may not be applicable in all situations. Electromagnetic propagation is affected by absorption and reflection
from structures, objects and persons.
