Guidance and manufacturer’s declaration - electromagnetic immunity
The MiniO
X

is intended for use in the electromagnetic environment specified below. The customer or the user of the
MiniO
X

Portable and mobile RF communications equipment should

cables, than the recommended separation distance

Field strengths from fixed RF transmitters, as determined
by an electromagnetic site survey,

should be less than the
compliance level in each frequency range.

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 MiniO
X
®
1
is used exceeds the
applicable RF compliance level above, the MiniO
X
®
1
should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the MiniO
X
®
1
.
b. Over the frequency range 150 kHz to 80 MHz, induced voltages across the sensor cable should be less than 0.4
Vrms, and, over the frequency range 80 MHz to 2.5 GHz, field strengths should be less than 3 V/m.
