Guidance and manufacturer’s declaration — electromagnetic immunity
The bed is supposed to be used in an electromagnetic environment where RF radio communication devices are used. The
electromagnetic interference between the RF communication device and the bed can be prevented by maintaining the
minimum distance between the two as recommended below in accordance with the maximum output and frequency of the
communication device.
