Eclipse Support

Before you start testing, instruct the patient to turn off all their electronic devices in order to minimize noise.

Now, look in your patient's ear to ensure no excess cerumen is present.
Clean the patient's skin on the high and low forehead and behind each ear on the mastoid.
Wipe off any excess abrasive gel and place your four electrodes.
If doing bone conduction, you can place the electrodes lower on the mastoid.
Connect the electrode cables.
You can twist the cables to help the common mode rejection and improve results.
Impedances below five kiloohms are acceptable.
