Appendix C
portable and mobile RF communications equipment and the 2008T hemodialysis machine
The 2008T hemodialysis machine is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the 2008T hemodialysis machine can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the 2008T hemodialysis machine 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 80 MHz and 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 absorption
and reflection from structures, objects, and people.

Product Improvement Policy

The 2008T hemodialysis machine was designed and built to comply with these product
specifications. It is the intention of Fresenius USA, Inc. to improve products continuously, a
process which may result in modifications to specifications or equipment produced in the
future. Such product improvements shall not incur any obligation to make similar changes or
improvements to equipment previously produced. These changes or improvements may or
may not be applicable or usable with previously produced equipment. Where possible,
improvements will be made available at reasonable prices. Any such improvement shall not
be construed as corrections of any perceived deficiency.
