Recommended separation distances between portable and mobile RF communications equipment and the
The AIDA INTERFACE II model 20 0921 32 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer or user of the unit can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the unit 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.
