level
Portable and mobile RF
communications equipment should be
used no closer to any part of the
Sonopuls 190, including cables, than
the recommended separation distance
calculated from the equation applicable
to the frequency of the transmitter.
Recommended separation distance
3 V
d = [3,5/3]√P
3 V/ m d = [3,5/3]√P
d = [7/3]√P
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,
