Recommended separation distances between portable and mobile RF
communications equipment and the Model Smart Control
The Model Smart Control is intended for use in an electromagnetic environment in
which radiated RF Disturbances are controlled. The customer or the user of the
Model Smart Control can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications equipment
(transmitters) and the Model Smart Control 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.
NOTE 1: At 80 MHz and 800 MHz, 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.
