Tymp+Ref button. Select the test ear by pressing either the Right or Left button. Cartoon mode will show an airplane on

The system will first check the probe fit and wait for
the pressure build up. The LED light on the probe will
pulse at a steady pace to indicate a correct fit. If the
ear tip fit is not correct, the LED light will blink at a
fast pace and an error message prompting you to
retry or cancel the test will appear on the screen.
Once a proper seal has been obtained, the test will proceed. A tympanometry test will be performed, followed by a reflex
measurement.
