1. Prepare the patient according to "Quick Reference for Preparing the Patient"
2. Select desired ASSR test protocol. ex.
3. If needed, adjust the rejection level to have a large size EEG displayed, but without the EEG
changing to red. Settings higher than 20 µV indicates a less than ideally relaxed patient (or electrical
noise interference), and less than perfect recording results are thus to be
expected. 80 µV or higher will not provide optimum results.

right clicking within the desired frequency pane.
