18 Advanced Options for DPOAE Testing
NOTE: The Advanced Options for DPOAE Testing section is reserved for those units
purchased as a diagnostic device. Instruments purchased as a screener can skip to Section
20.
The Advanced Options menus permit modification of the test parameters and pass criteria
for the customizable DP protocols. Changes to the protocol should be made only by
qualified personnel, usually the administrator. If you are not familiar with the use of these
variables, do not attempt to change the protocols. Changes to any of these characteristics
may yield test results that differ from those obtained in other test modes.

The ERO•SCAN
instrument comes with pre-programmed protocol settings. See Appendix
D for the manufacturer settings of these protocols. Test protocol changes are saved in the
non-volatile memory so the settings will be retained even when the battery is discharged
temporarily.
