Recording terminated!
The current measurement was stopped because there is
not enough space available to store the data. Push the
button R

to save or delete some of the past
measurements and get free space on the hard disk.
EEG storage left: < 100 hours The available capacity is less than 100 hours. It is
possible to start measurements but it is recommended to
delete measurements in the “Review mode”. If necessary
you can save the measurements beforehand.
Impedance
Due to high impedance values or impedance differences,
a classification is impossible. Check the position of the
electrodes on the patient's head and the connections to
the patient cable. Press the pad gently or glue on a new
electrode.
50 Hz or 60 Hz
AC artifacts occur. In case of excessive artifact load, the
signal is not evaluated. If the error persists please contact
support (see contact on the back of the cover page).
EMG
Due to excessive EMG artifacts, a classification is
impossible. (EMG = electromyogram, intensity of electrical
muscle activity)
Undiff. EEG
This message will only be displayed with the occurrence
of an undifferentiated EEG in the case where measuring
takes place in children aged 12 months or less. Such an
undifferentiated EEG cannot be classified apart from E

. In the case of the occurrence of a differentiated EEG,
this message will not be displayed, but instead classified
even in the case of children aged 12 months or less.
