It is recommended to use portable and
mobile HF communication equipment
around the bed in distances defined
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.
