Working clearances

The UNIT is intended for operation in an electromagnetic environment,
where radiated RF interference is checked. The customer or the user of
the UNIT can help prevent electromagnetic interference by duly
observing the minimum distances between portable and/or mobile RF
communication devices (transmitters) and the UNIT. These values may
vary according to the output power of the relevant communication device
as specified below.

For transmitters whose maximum nominal output is not specified in the
above table, the recommended working clearance d in meters (m) can be
determined using the equation in the corresponding column, where P is
the maximum nominal output of the transmitter in watts (W) specified by
the transmitter manufacturer.
Remark 1
An additional factor of 10/3 is applied when calculating the recommended
working clearance between transmitters in the 80 MHz to 2.3 GHz
frequency range in order to reduce the probability that a mobile/portable
communication device unintentionally brought into the patient area could
lead to interference.
Remark 2
These guidelines may not be applicable in all cases. The propagation of
electromagnetic waves is influenced by their absorption and reflection by
buildings, objects and persons.
