distance in metres (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.
b
Interference may occur in the
vicinity of equipment marked
with the following symbol:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption
and reflection from structures, objects and people.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast
cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to
fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field
strength in the location in which the model AID-173SHR is used exceeds the applicable RF
compliance level above, the model AID-173SHR should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the model AID-173SHR.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
