Working clearances

UNIT
The is intended for operation in an electromagnetic environment
where radiated HF 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 HF communication
devices (transmitters) and the
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
The higher frequency range applies at 80 MHz and 800 MHz.
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.
