6) After testing at all the selected frequencies for the ear, the ES3 will
examine the other ear to see if testing has been completed for each
frequency. If the opposite ear has not been tested, ES3 will select the
opposite ear, and begin testing in the manner described beginning with
step 1. If both ears have been tested, the test is complete and ES3 will
return to the manual audiometry mode.
Automatic Threshold Test Error Conditions
If an error is encountered during an automatic threshold test, the ES3 will stop the
test and indicate the error condition. The operator may re-instruct the patient via
talk over mode and resume testing, or return to manual audiometry mode. Table 4
lists the error conditions that the ES3 detects.

Button Held Patient is holding down response button.
False Response
Patient pressed response button outside the valid response
“window” or when no tone was presented.
Inconsistent
Results
A valid threshold was not obtained. Testing stopped at the
point where the error occurred.
Validity Error The 1k and 1k/V thresholds differ by more than 5 dB.
Automatic Threshold Audiometry Options
Frequency Selection
Frequencies used during automatic threshold testing are the same as those for a
manual test (see Selecting Frequencies).
Frequency Presentation Order
Frequency presentation order may be changed via the menu sequence ⌐S
ETUP
⌐AUDIOMETRY SETUP ⌐AUTO THRESHOLD ⌐FREQUENCY ORDER. The default sequence
is 1k/V, 500, 1000, 2000, 3000, 4000, 6000, and 8000 Hz. Only those frequencies
selected for testing will be used.
To change presentation order, move the highlight with the {◄} / {►} or {▲} / {▼}
keys and press {Ο} to select a frequency. Move it to any position in the list using
the {◄} / {►} or {▲} / {▼} keys, and press the {Ο} key to place it at that position.
When all frequencies are in the desired presentation order, press {Menu} to exit.
