Testing the patient - Fitting the ear tip on the probe 16
• When calibration/impedance testing has been successfully completed, testing begins automati-
cally. The LED flashes green during testing. If it flashes red, noise levels are high and/or the probe
may not fit correctly.
• The test as it progresses is shown on the display.
Duration
• When the test is completed, the result is shown on the display. To interpret the test results, see
“Interpreting test results” on page 11.
• To cancel at any stage during the test, press STOP.
• To continue the test, press the OK button. You can now scroll to select the patient's other ear on
the screen and, if required, reposition the patient so that you can test the other ear.
• Before you continue testing the other ear, check to make sure that the probe is clean. See also
“Maintenance” on page 25.
