 Do not use portable and mobile HF
communication equipment near the bed.
 Observe the distances indicated below.
Recommended distances:
d = 1.2 P
d = 1.2 P 80 MHz to 800 MHz
d = 2.3 P 800 MHz to 2.5 GHz
P is the rated maximum output power of the
transmitter in Watts (W) defined by the transmit-
ter's manufacturer.
d is the recommended separating distance in
metres (m).
 Ensure that the field intensities of per-
manent HF transmitters determined by
the summary of electromagnetic charac-
teristics for the given place
a
do not
exceed the satisfactory level
b
in each
frequency range.
Interferences are possible in the vicinity of the
instrument marked with the following symbol:

It is not possible to accurately indicate field intensities from permanent transmitters (e.g. radio base stations of
the radio, phones and ground mobile and amateur radio stations, AM and FM radio and television broadcasting).
To assess the electromagnetic environment for permanent HF transmitters, take into account the on-site electro-
magnetic characteristics.
If the measured field intensity is higher than the pertinent satisfactory HF level stated above, observe whether
the bed is functioning normally.
If any abnormal properties are observed, move or relocate the bed.

The field intensity in the entire frequency range from 150 kHz to 80 MHz should be lower than 3 V/m.
NOTE With 80 MHz and 800 MHz, the higher frequency range is applicable.
NOTE The absorption and reflection of buildings, objects and people will influence electromagnetic
propagation.
