Enclosure insulation

In order to confirm ongoing electromagnetic compliance (IEC 60601-1-2), the integrity of the enclosure insulation can be
assessed by placing the generator on a sheet of metal foil and measuring the current between the foil and ground when the
generator is switched on using a digital multimeter. When carrying out this test the operator should stand at least two feet
away from the generator to ensure a stable reading. The leakage current reading should not exceed 0.1uA.

Repair actions

The Ultravision system is subject to precise calibration as part of the manufacturing process. All servicing and repairs must
be conducted by the manufacturer so as not to void any warranty or potentially compromise the safety and/or performance
of the device. Do not attempt to open or repair the device.
If any of the inspection methods listed above suggest that the Ultravision or one of its reusable accessories are damaged,
take the generator and/or recharger out of circulation immediately and contact your local distributor to arrange repairs.
In some instances it may be possible to send a replacement part but complex repairs will necessitate the unit being returned
to the manufacturer.
