Eliminating electromagnetic interferences

The unit is only designed for operation in the following electromagnetic environment:
Radio frequency emission according to CISPR 11, group 1, class B.
Group 1 means that the ergometer exclusively uses HF energy for its internal function. This
makes its HF emission very low and unlikely to disturb electronic devices in the vicinity.
Class B means that the ergometer is suitable for use in any facilities including residential areas,
even if it is directly connected to the public mains that also supplies residential buildings.
The unit is resistant to jamming in an electromagnetic environment if the following prerequisites
are met:
The voltage corresponds to the typical business or hospital environment, and the humidity is

at least 30%, especially if the floors are synthetic.
If any disorders should occur nevertheless, especially in the vicinity of devices labelled with the
symbol "non-ionic electromagnetic radiation", check the recommended minimal distance
according to the following table. More information is given in the service manual.
