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
transmitter's
manufacturer.
d is the recommended separating distance
in metres (m).
Ensure the field intensities of
permanent HF transmitters
determined by the summary of
electromagnetic characteristics for
the given place 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:

a 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
electromagnetic
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.
b 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
