INTRODUCTION
This Technical Reference Manual Slot provides information for the maintenance and service of the
Datex-Ohmeda S/5 EEG Module, M-EEG and Datex-Ohmeda S/5 EEG Headbox, N-EEG. The EEG
module is a single width plug-in module designed for use with the S/5 monitors. Later in this
manual modules can be called w/o system name S/5.

Technical Reference Manual
for information related to system e.g. related
documentation, conventions used, symbols on equipment, safety precautions, system description,
system installation, interfacing, functional check and planned maintenance.
The EEG module and the EEG headbox together measure:
•
electroencephalography (EEG)
•
spontaneous facial muscular activity with frontal electromyography (FEMG)
•
auditory evoked potentials (AEP)
The EEG Headbox, N-EEG, is responsible for EEG and FEMG signal amplification, filtering and
digitalization and electrode impedance measurement. It is situated close to the patient’s head. The
Headbox has connectors for the EEG leads, either for a referential or a bipolar montage, and for the
AEP stimulation earphones.
The EEG module M-EEG creates auditory stimulus pulses and takes care of AEP signal processing.
It has one connector for the EEG headbox.
