OtoRead™ DPOAE

1. Test Environment
   The ideal test environment is a quiet room.
   
   
2. Preparing the Patient
   Place the patient in a position that will allow easy access to the ear canal. Use the shirt clip on the probe cable to secure the probe to clothing or bedding. The patient should remain still and quiet while the test is being performed. If a baby is tested, ensure it is sleeping or in quiet relaxed state. Sucking, blinking, crying or movement may affect testing.
   
   
3. Preparing the Equipment
   Turn on the OtoRead™ by pressing the down button
   
   
   To change the selected protocol press CHANGE at the Main Menu. The Change Protocol Display will appear. Use the CHANGE arrow buttons to change the selected protocol. Press theUP arrow to return to the Main Menu to begin testing.
    
   
   To begin a test, insert the probe into the ear and select either the LEFT or RIGHT arrow key to indicate the ear to be tested.
   
   
   
4. The Probe
   Place the probe in the ear and then press the LEFT or RIGHT arrow key to begin the test – the test will proceed automatically if the probe fit is stable.
   
   
   To replace the probe tube, use the ear tip to grasp the probe tube (the clear plastic tube) and twist slightly while pulling the probe tube straight out of the probe head.
   
   
   Dispose of the used probe tube immediately to avoid confusing used tubes with new tubes. Take a new probe tube from the package and insert the tube into the probe head until it is fully seated. A properly inserted probe tube will snap securely into place when it is fully seated in the probe head.
