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

100 11.667 11.667 23.333
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.
