Select the test ear by pressing either the Right or Left button, or Right + Left for binaural testing. Binaural
testing is available when headphones, insert phones or two ear probes are connected (if stimulating at low
intensity levels only).
Make sure the patient is sitting or lying down comfortably.
An impedance check will be performed prior to measurement. If impedance is below 6 k ohm, the start button
will become available. You can configure the settings for the test to autostart if the impedance is lower than
4 k ohm. If impedance is higher than 6 k ohm but below 12 k ohm, a skip button will become available. An
impedance below 6 k ohm is recommended for best test results.
