The DSO 364 model is intended for operation in
an electromagnetic environment where HF dis-
turbances are monitored. The customer or user
of the DSO 364 model can help to avoid electro-
magnetic disturbances by observing the mini-
mum clearance between portable and mobile HF
telecommunication devices (transmitters) and
the DSO 364 model – depending on the output
power of the communication device as discussed
below.

For transmitters whose nominal output is not
specified in the above table, the distance can be
determined using the equation in the respective

of the transmitter in watts (W) as specified by the
transmitter manufacturer.
