Speaker test
The calibration is followed by a speaker test to make sure that the two speakers func-
tion correctly.
The test starts automatically when calibration is completed.
“Incomplete” message
If the message
Incomplete
appears:
•
Refit the probe and make sure that it fits correctly.
•
Press the
Start
button to restart the test.
If the calibration fails due to large ear canal volume (for example, due to a PE tube in
the patient's ear), and if the
Manual start
option is enabled in
Test Settings
, then a
double arrow appears on the result screen. Press the double-arrow to start the meas-
urement with maximum calibrated output levels.

The DPOAE test
The test as it progresses is shown on the display. The test ear and the frequency cur-
rently being tested is shown at the top of the screen.
If
Child Mode
is activated, an animated car is displayed on the screen during testing.
(See
.)
The progress bar under the animated picture is green if the test conditions are good
and it is red if there is too much noise. Noise can come from the environment or the
patient.
The bar gets longer as each test frequency in the sequence is completed.
