Dual Format Display
You can display the EEG in two formats simultaneously. Enable dual format from
the DISPLAY FORMAT menu. This allows the display of DSA and analog, DSA
and trend, trend and analog, or two different trends. In addition, the second
display zone can be used to show recalled snapshots of DSA or trends,
simultaneously with live DSA or trend data.

EMG Display
There is one EMG channel that can be used to monitor muscle electrical activity.
Select EMG with the EMG ON /OFF key in the Montage menu. The ON section of
the key will be highlighted when it is on. Touch the key and select OFF to turn off
the EMG channel. The OFF portion of the key will be highlighted.
Although EMG uses only one channel, the EMG trend is displayed in each
channel so it can be used to compare against EEG when dual format is on.
