Portable and mobile RF
communications equipment should
be used no closer to any part of
Cefar TENS, than the recommended
separation distance calculated
from the equation applicable to
the frequency of the transmitter.
Recommended separation distance

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, a should
be less than the compliance level in
each frequency range.
Interference may occur in the vicinity
