Manage (remove) devices that are highly susceptible to EMI.
Lower power from internal EMI sources under hospital control (i.e., paging
systems).
Label devices susceptible to EMI.
Educate staff (nurses and doctors) to be aware of, and to recognize, potential EMI
related problems.
The following table provides the recommended separation distances (in meters)
between portable and mobile RF communications equipment and the ATS.
The ATS is intended for use in the electromagnetic environment on which radiated RF
disturbances are controlled. The customer or the user of the ATS can help prevent
electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communications equipment (transmitters) and the ATS 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 equitation 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
These guidelines may not apply in all instances. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
