Eclipse Additional Information

6.6.4 Electrode placement

After having prepared the skin, place an electrode on each mastoid or earlobe (blue electrode lead on left
side, red on right side) one at the vertex or hair-line (white electrode lead) and the ground connection (black)
can be placed on the low forehead or on the cheek. The placement of the ground electrode is not very criti-
cal.
Hint The electrode cables must be as close together as possible and must be routed from the patient to the
Preamplifier in a way where they do not get close to any other electrical cables or equipment, including the
cables from the Eclipse and the headphones.
Note Do not press in the middle of the disposable electrodes when mounting, since this will cause gel to be
pressed out and the adhesive below the white line will not stick. This will cause the electrode to loosen from
the skin and may cause very high impedances during testing. Mount the disposable electrode by securing it
to the position by firmly pressing the fingertip along the white border around the edge of the electrode pad.

6.6.5 Insertion of the Eartips

1. Different sizes of ear tips are available.
2. Make sure that the end of the black tube is not covered by the yellow foam when you roll the tip into the
smallest diameter possible.
3. Insert the tip well into the ear canal. The correct insertion depth into the ear canal is obtained when the
rear edge of the tip is 2-3mm inside the entrance of the ear canal.
4. Secure the tip in the ear canal until foam expands.
Use a new pair of ear tips for the next patient.
