Specifications – Recommended Separation
Distances between Portable and Mobile RF
Communications Equipment and the Empi Active Device
The Empi Active device is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the
Empi Active device can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications equipment
(transmitters) and the Empi Active device 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 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.
