(transmitters) and the Patient Data Module 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.
Compliant cables and accessories
WARNING
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 table below lists cables, transducers, and other applicable accessories with which
GE claims EMC compliance.
NOTE
Any supplied accessories that do not affect EMC compliance are not included.
