Recommended safety distances between portable and mobile HF communication equipment
and the Précise 6000
The
Précise 6000
is intended for operation in an electromagnetic environment with controlled HF
interferences. The customer or user of the
Précise 6000
can help to avoid electromagnetic
interferences by maintaining minimum distances between the portable and mobile HF
communication equipment (transmitter) and the
Précise 6000
, according to the maximum output
power of the communication equipment, as recommended below.

For transmitters for which the rated power is not contained in the tale above, the distance can be
calculated using the equation for the corresponding column, whereby P represents the rated power
of the transmitter in Watt (W), specified by the transmitter manufacturer.
Note 1
For calculation of the recommended safety distance for transmitters in the frequency range from 80
MHz to 2,5 GHz an additional of 10/3 was used, in order to reduce the likelihood that a mobile /
portable communication unit, that has unintentionally been brought near the patient, will trigger an
interference.
Note2
These regulations may not apply in all situations, The propagation of electromagnetic waves is
influenced by the absorption and reflection by building, objects and persons.
