guidelines
Portable and mobile wireless receiving
and transmission equipment should not
be used at a distance to the Tel-O-
Graph
(including wires) of less than the
recommended protection ratio calculated
for the equation that applies to the
transmission frequency.
Recommended safety distance:
d = 1,2 * P(W) for 80 Mhz to 800 Mhz
d = 2,3 * P(W) for 800 Mhz to 2,5 Ghz
3 V/m
where P = maximum nominal output of
the transmitter in watts as per the
transmitter manufacturer's specifications
and d = recommended protection ratio in
meters (m).
The field strength of stationary radio
wireless transmitters should be lower
than the compliance level at all
frequencies, as shown by an on-site
examination. Interference is possible in
the vicinity of devices bearing the graphic
symbol "nonionising radiation".
