P
is the max nominal exit potential
of trasmitter in Watt (W) according
to the trasmitter manufacturer and
d
is the separation distance
recomended, in meter (m).
RF fixed trasmitter field intensity,
definied with an electromagnetic in
loco survey, must be lower than the
comformity level for each
frequency

proximity of device with this symbol:
NOTE1: 80 MHz and 800 MHz, is applied the separation distance for the highr frequency interval
