When using insert phones, ensure the ear tip adaptor is connected
to a disposable ear tip (9mm green recommended). Insert the ear
tips into the holes until the outer edge of the mushroom sits f lush
with the outer edge of the hole. Do not push the ear tip in too far or
it can get lodged inside.
If using the probe, ensure a disposable ear tip is connected (blue
recommended) bef ore inserting it into the hole. Block the other hole
of the Pass-Checker before conducting the test.
4. Switch on the Pass-Checker by pressing the power button. The
amber LED lights up when the Pass-Checker is turned on.
The Pass-Checker has an auto-off f unction. If you perform
repeated tests during troubleshooting, make sure that the Pass-
Checker is still switched on during your tests.
5. Perform a standard binaural or monaural (for probe) Automated
ABR test.
6. The test should proceed quickly through the impedance and
measurement phases ending in a Pass result for both ears (one
if probe used). If the test does not Pass or the test cannot go
further than the Impedance check, there is a potential issue with
the system.
