Electromagnetic emissions – Ultravision Generator
With reference to the 4
th
Edition of IEC 60601-1-2:2014 The Ultravision generator is intended for use in the Special Environ-
ment of high powered medical electrical equipment associated with powered surgical devices. The customer or the user of
the Ultravision generator should assure that it is only used in such an environment.

RF emissions CISPR 11
Group 1
The Ultravision generator uses RF energy only for
its internal function. Therefore, its RF emissions are
very low and are not likely to cause any interfer-
ence in nearby electronic equipment. RF emissions

Class A
The Ultravision generator is suitable for use in all
establishments other than domestic and those
directly connected to the public low-voltage power
supply network that supplies buildings used for
domestic purposes.
