Interacoustics Sera Instructions For Use Manual page 66

Please note: The Pass-Checker battery should only be replaced by an authorized Interacoustics
representative. Damage to the Pass-Checker electronics resulting from an attempt to change the battery by
someone other than an authorized representative will not qualify for repair under the product warranty.
If no Pass-checker is available to perform the Automated ABR integrity check, you can perform the testing
on yourself.

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 flush
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) before 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 function. 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.
