Table 8-5. Recommended separation distances between
portable and mobile RF communications equipment and the Visual-ICE System
Recommended separation distances between
portable and mobile RF communications equipment and the Visual-ICE System
The Visual-ICE 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 System can help
prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Visual-ICE System 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.
