Choosing an EEG Electrode Montage

1To activate one of the five pre-configured electrode montages, select the arrow beside the label in the EEG Impedance/Montage window and choose a montage from the list.

2Attach the electrodes as illustrated in the EEG Impedance/Montage window.

The five default electrode montage configurations can be modified and renamed in Configuration Mode.

Montage Name	EEG1+	EEG1-	Label1	EEG2+	EEG2-	Label2
Mont.A	Fp1	T3	Fp1-T3	Fp2	T4	Fp2-T4
Mont.B	O1	T3	O1-T3	O2	T4	O2-T4
Mont.C	F3	C3	F3-C3	F4	C4	F4-C4
Mont.D	C3	P3	C3-P3	C4	P4	C4-P4
Mont.E	Fp1	T5	Fp1-T5	Fp2	T6	Fp2-T6

The electrode locations are labeled according to the international 10-20 electrode placement system.

Changing the Impedance Limit

The impedance limit can be set for all electrodes simultaneously in the Setup EEG menu, or in the EEG Impedance/Montage window using the pop-up keys. If the limit is exceeded during monitoring, an INOP will appear and the graphic impedance indicator will change.

To change the impedance limit, either

♦use the pop-up keys that appear with the EEG Impedance /Montage window, or

♦in the Setup EEG menu, select Impedance Limit to call up a list of selections between 1 and 30 kOhm, then select the required limit from this list.
