equipment should be used no closer to
any part of the SE series LED Display,
including cables, than the recommended
separation distance calculated from the

Where "P" is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter manufacturer
and "d" is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
survey, should be less than the compliance
level in each frequency range.
Interference may occur in the vicinity of
