When CSAs are shown embedded on the Main Screen, select the CSA to show the pop-up keys. When
the CSA is shown in a window over the current screen, the pop-up keys are always displayed.
Changing EEG Settings
Be aware that any changes made to EEG settings apply to both EEG channels.
Switching EEG Numerics On and Off
Each EEG numeric can be individually switched on or off in the Setup EEG menu.
1 In the Setup EEG menu, select the numeric label.
2 Select On or Off to switch between the settings.
Changing the Scale of the EEG Waves for Display
This only changes the visual appearance of the wave. It does not affect the signal analyzed by the
monitor or printed in reports or recordings.
1 In the Setup EEG menu, select Wave Scale to call up a list of wave scales.
2 Select the required scale from this list.
Scaling information is displayed with each EEG wave.
The CSA contains the following information
Status line
Lead label for example, Fp1-T3, Fp2-T4
CSA label CSA1 or CSA2 according to EEG channel
Montage label for example, Montage A
Filter settings for example, 1-30 Hz
Buffer label and time the buffer and interval between spectral lines on the CSA
Current SEF Threshold can only be changed in Configuration Mode
Spectral lines
The energy at each frequency is computed and displayed as a spectral line
Trendlines
EEG values are sampled at configured time intervals and displayed as color-coded trendlines.
Trendlines are available for the three frequency numerics (SEF, PPF, MDF)
