Montage Rules A notch filter setting may be turned on and off during data acquisition and during review. When active/reference pairs 1A-Ref, etc. are used, their references cannot be changed during review. Usually these channels are unlinked and are used to monitor non-EEG signals such as ECG or respiration. If an active/reference pair is used, the active electrode cannot be used in any other channel. For example, 4A-Ref and 4a-C3 cannot exist in the same montage. Montages used during a recording are permanently saved with the record, although you may select another montage for viewing at any time during review. Even if you change the montage while reviewing, you can still re-display the EEG as originally recorded.
Cadwell Easy III – Version 3.5 114 Average References Average References can be used as a channel’s reference input, and can be defined from head pattern or grid electrodes.
