Portable and mobile RF communications
equipment should not be used closer to
any part of the equipment, including ca-
bles, than the recommended separation
distance calculated from the equation ap-
plicable to the transmitter frequency.

(W), according to the transmitter manu-
facturer and

ration distance in metres (m).
The field strengths of fixed RF transmit-
ters, as determined by an on-site electro-
magnetic investigation, should be below
the compliance level in each frequency
range.
Interference may occur in the vicinity of
the device marked with the following
symbol:
NOTE 1 At 80 MHz and 800 MHz, the highest frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflections from structures, objects and people.
a) The field strengths of fixed transmitters, such as base stations for radiotelephones (cellular/wireless) and land mo-
bile radios, amateur radio, AM and FM broadcasting, and TV broadcasting, cannot be predicted theoretically with
accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an on-site electromagnetic investi-
gation should be considered. If the field strength, measured at the location where the Echodia Series equipment is
used, exceeds the applicable RF compliance level above, the Echodia Series equipment should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be required, such as reorienting or
repositioning the Echodia product line.
b) Above the frequency range of 150 kHz to 80 MHz, field strengths should be less than 3V/m.
Recommended separation distances between portable and mobile RF devices and the range device
Echodia
The Echodia range of devices is intended for use in an electromagnetic environment in which radiated RF interfer-
ence is controlled. The customer or user of the device can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and Echodia Series
devices, as recommended below, based on the maximum transmit power of the communications equipment.

For transmitters whose maximum rated transmit power is not given above, the recommended separation distance
d
in
metres (m) can be estimated using the equation applicable to the frequency of the transmitter, where
P
is the maxi-
mum transmit power characteristic of the transmitter in watts (W), according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the highest frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflections from structures, objects and people.
