D. DISTANCE FROM THE SOURCE
EM energy rapidly becomes more intense as you get closer to the source. For this
reason, EMI from hand-held devices is of special concern. (See C.1 above) A per-
son using one of these devices can bring high levels of EM energy very close to
your chair without you knowing it.
E. REPORT ALL SUSPECTED EMI INCIDENTS
You should promptly report any unintended movement or brake release. Be sure
to indicate whether there was a radio wave source near your chair at the time.
