VisionAire™
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.
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.

The VisionAire uses RF energy only for its internal
function. Therefore, its RF emissions are very low
Group 1
and are not likely to cause any interference in nearby
electronic equipment.
The VisionAire is suitable for use in all
Class B
establishments, including domestic establishments
and those directly connected to the public low-
voltage power supply network that supplies buildings
used for domestic purposes.
