First I would like to thank the group.As usual the open sharing
of ideas provides a lot of insight to me.
I have one question though - I am particularly interested in
the requirements for EN55024.
Has anyone changes their ESD procedures as a result of the
internal ESD requirement of the spec?
Hello,
Does anyone in this august group apply ESD discharges INTERNAL

Hello EMC standards gurus!!!
I am being told that the use of uncertified radios (think WIFi) in the field
is permitted
as long as there are no commercial transactions involved.

Late to the party - but agree with James. Look to the USB cable first (as an
obvious source). Incidentally try to use a robust
USB peripheral and avoid the USB memory sticks. We use external USB powered
