devices should not be used closer to any
part of the device, including cables, than

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 devices are used,
exceeds the applicable RF compliance level above, the Echodia Series devices should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be required, such as reorienting or reposi-
tioning the Echodia Series devices.
b) Above the frequency range of 150 kHz to 80 MHz, field strengths should be less than 3V/m.
