2) Fit the Probe (Using Ear Probe Cable) a. Check the patient’s ear canal and select the appropriate ear tip size. b. Push the ear tip onto the probe tip until it sits against the probe. Orient large ear tips so that their raised side faces the probe. Orient small ear tips so that their enlarged side faces the probe (see Figure below). Large Ear Tip
Small Ear Tip
Data Entry: • Use the alphanumeric keypad to enter numbers and letters. • Use the < and > arrow keys on the keypad to move the cursor backwards and forwards. SETUP OF THE DEVICE Verify that the ABR notch filter and stimulus level are set according to your facility’s protocol. (Select “Options” → “ABR Configuration”) preparation for testing 1) Connect Ear Probe Cable to Echo-Screen Ear Probe socket (for use with ear tips) OR Connect Y Probe Cable to Echo-Screen Ear Probe socket (for use with Echo Couplers) 2) Use Test Cavity to conduct probe test prior to screening (Select “Options” → “Self test” → “Probe test”) Note: One probe test per day is recommended prior to screening patients. 3) Connect ABR cable to Echo-Screen ABR electrode socket.

QUICK REFERENCE GUIDE AABR® TECHNOLOGY AABR Screening Procedure (cont’d) III. Start Screening/Monitor Progress 1) Select “ABR” from Measure display and press OK to continue (See Figure below).
a. AABR testing with Ear Probe Cable (ear tips): • Select “Comments” to enter additional information regarding the screen and press OK (See left Figure below). Add a new comment or select a default comment. • Select the ear to be tested (Right or Left) and press OK to start the test (See left Figure below). Note: An impedance check is automatically conducted prior to testing (See right Figure below). Press OK to begin testing.
3) At the completion of the test, a PASS or REFER result automatically displays (See Figure below).
a. Press OK to test another ear or to view, print, and transfer results. printing results via infrared (wireless) 1) Select “Print results” from the Main Menu display (See left Figure below). 2) From the Patient List display, select the patient whose results are to be printed (See right Figure below).

Note: An impedance check is automatically conducted prior to testing (See right Figure below). Press OK to begin testing.
7) Select the result(s) to be printed from the Results menu and press OK to print.
NOTE: Vertex (White) and Nape (Red) impedances must be below 12,000 Ohms for testing to proceed. Balance impedance must be below 4,000 Ohms for testing to proceed. 2) As testing proceeds, the status is indicated on the display (See Figure below). a. Time = screen duration ABR = probability of detecting an ABR signal EEG = amplitude of total registered potential. b. Press to pause the test or to cancel the test.
