Follow these techniques to help identify the sources, and to increase the
immunity towards parasitical noise:
•
Verify the power supply and all portable multiple socket-outlets are off the floor and in a dry
location.
•
If parasitic noise is present on the EEG waveforms, try to identify possible culprits by
disconnecting nearby equipment from the common power source.
•
Lay out the interconnection cables as far as possible from the cables being used by nearby
equipment.
•
Verify the Power cord integrity. Do not use portable multiple socket outlets that are not properly
grounded.
•
Do not use power outlets without a protective ground
•
When isolation transformers are used, ensure that the Medical System is properly grounded.
