For transmitters rated at a maximum output power not listed above, the recommended separation
distanced 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) accordable
to the transmitter manufacturer.
NOTE I 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.
Recommended separation distances between
portable and mobile RF communications equipment and the model UDS-A
The model UDS-A is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the model UDS-A can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the model UDS-A as recommended
below, according to the maximum output power of the communications equipment.
