Guidelines and manufacturer's declaration - Electromagnetic immunity
The healthcare bed is intended for use in the electromagnetic environment specified below. The
customer or user of the healthcare bed should ensure that it is used in such an environment.

Portable and mobile radios should not
be used at a shorter distance from
the nursing bed, including the cables,
than the recommended protective
distance calculated according to the
equation applicable to the
transmission frequency.
Recommended protective distance:
for 80 MHz to 800 MHz
for 800 MHz to 2.5 GHz
With P as the rated power of the
transmitter in watts (W) according to
the transmitter manufacturer's
specifications and b d as the
recommended protective distance in
meters (m).
The a field strength of stationary radio
transmitters should be less than the
compliance level at all frequencies
according to a field study.
Interference may occur in the vicinity
of equipment bearing the following
symbol.
NOTE 1 The higher frequency range applies at 80 MHz and 800 MHz.
NOTE 2 These guidelines may not be applicable in all cases. The propagation of electromagnetic
quantities a is influenced by absorptions and reflections from buildings, objects and people.
The field strength of stationary transmitters such as base stations of radio telephones and land
mobile radios, amateur radio stations, AM and FM radio and television transmitters cannot
theoretically be predicted accurately. In order to determine the electromagnetic environment with
respect to the stationary transmitters, an investigation of the location should be considered. If the
measured field strength at the site where the healthcare bed is used exceeds the above
compliance levels, the healthcare bed should be monitored to demonstrate proper functioning. If
unusual performance characteristics are observed, additional measures may be required, such as a
change in orientation or a different location of the healthcare beds.
