Table X-4 Recommended Separation Distances Between Portable and Mobile RF
Communications Equipment and the X12+ Transmitter.
The X12+ Transmitter is intended for use in the electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the X12+ Transmitter can help to prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the
X12+ Transmitter 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 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 the absorption
and reflection from structures, objects, and people.
