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 Sana Sedeo 150/250 exclusively uses HF energy for its internal func-
tion. This makes its HF emission very low and unlikely to disturb electronic devices in the vicinity.
Class B means that the ergometer Sana Sedeo 150/250 is suitable for use in any facilities including residen-
tial 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.
Recommended safety distances between portable and mobile HF telecommunication devices and
the Sana Sedeo 150/250
The Sana Sedeo 150/250 is designed for operation in an electromagnetic environment with controlled HF dis-
turbance. The customer or user of the Sana Sedeo 150/250 can help avoid electromagnetic disturbances by
keeping the minimum distance between portable and mobile HF telecommunication devices (senders) and
the ergometer, depending on the output performance of the communication device as indicated below.
