Recommended separation distances between portable and mobile RF communications equipment and the VisionAire
The VisionAire is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the VisionAire can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the VisionAire as recommended below, according to the
maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be
estimated using 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 manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for 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.
Guidance and manufacturer’s declaration – electromagnetic emissions
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.
Emissions test Compliance Electromagnetic Environment guidance
RF emissions
CISPR 11
Group 1
The VisionAire uses RF energy only for its internal
function. Therefore, its RF emissions are very low
and are not likely to cause any interference in nearby
electronic equipment.
