To view the EEG tracing:
With the patient’s CFM tracing displayed, touch
EEG
. When you open the EEG view
while recording when there is more the three hours of CFM data, the CFM 6000
switches to playback mode, so the displayed EEG data is not real-time.
To monitor live EEG data while recording, touch
LIVE
to return to real-time display.
Navigating an EEG Tracing

tracing, depending on the EEG speed setting. By default, it shows six seconds at 30
mm/second. See

on page 20 for instructions on
changing the speed setting.
