Electromagnetic Compatibility
2031504-159D MAC™ 800 B-5
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
These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures,
objects, and people.
EMC-Compliant Cables and Accessories
WARNING
USE OF CORRECT ACCESSORIES — The use of
accessories, transducers and cables other than those
specified may result in increased emissions or decreased
immunity performance of the equipment or system.
The following table lists cables, transducers, and other applicable
accessories which GE Healthcare claims are EMC compliant.
NOTE
Any supplied accessories that do not affect EMC compliance are not
included.
