VisionAire Family
Guidance and Manufacturer’s Declaration–Electromagnetic Immunity
The VisionAire is intended for use in the electromagnetic environment specified below. The customer or the user
of the VisionAire should assure that it is used in such an environment.

closer to any part of the VisionAire, in-
cluding cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of
the transmitter.

where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter manufac-
turer and
d is the recommended sepa-
ration distance in metres (m).
Field strengths from fixed RF transmit-
ters, as determined by an electromag-
netic 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 VisionAire is used ex-
ceeds the applicable RF compliance level above, the VisionAire should be observed to verify normal operation.
If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating
the VisionAire.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
