1. Place the electrodes on the patient as follows:
Red
On the nape of the neck
Black
On the cheekbone (common or ground electrode)
White On the upper part of the forehead
2. Make sure that the electrodes fit tightly on the skin.
Note
•
The hydrogel of the electrodes can dry out. Make sure that used packages are closed properly. Dried out hydro-
gel may cause unexpectedly high electrode impedance. If this is the case, change the electrodes.
Note
•
The black electrode (common or ground electrode) could alternatively be placed on the baby's chest or
shoulder. The red and white electrodes must, however, be placed as stated, i.e. on the nape of the neck and on the
upper part of the forehead, respectively. Other electrode placements have not been validated.

Fitting the ear couplers
Warning
•
Never place the red and blue ear coupler adapters directly in the ear canal. Use them only with the ear
couplers fitted.
Note
•
Use the ear couplers only with the ear coupler cable - not with the ear probe.
