Guidance
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
d= 3.5 √P 150 KHz to 80 MHz
V1
d= 3.5 √P 80 MHz to 800 MHz
E1
d= 7 √P = 80 MHz to 2.7 GHz
E1
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
20xx
should be less than the compliance
level in each frequency range.
Interference may occur in the
vicinity of equipment marked with
