John, Massimo

I guess the EN 55014-1,2 would be more applicable regarding EMC in Europe.
However the ETSI depending on the answers from Massimo can cover already a
good part and should be seen in combination to the EN.

In Europe, the Generic EMC Standards would apply plus whatever ETSI
standards cover the radio part. For safety, I suppose EN60335-1 if the
propulsion is electric.

Yes. Unless it's actually an induction system rather than an EM-wave
system, in which case the answer gets less definite. What frequency does
the transmitter use?

You probably need to measure the magnetic field if the transmitter has a
loop antenna, not the electric field, so the 3m/10m distance requirement
is not relevant. But there probably needs to be a specified distance,
maybe 1 m.

Immunity is VERY important. We don't want these things running amok
every time an EM disturbance occurs!
