Table 3: Guidelines and manufacturer‘s declaration – Electromagnetic immunity – For all ME de-
vices and ME systems that are not intended for life support
The sentida nursing home bed is intended for operation in an electromagnetic environment as specified
below. The customer or user of the sentida nursing home bed should ensure that it is operated in such
an environment�

symbol.
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not be applicable in all cases. The propagation of elec-
tromagnetic quantities is influenced by absorption and reflections of the buil-
dings, objects and people.
