Max (dB)
Select the desired maximum level (up to 110 dB).
Warning
•
Be careful when you enter the Max setting, so as
not to expose the patient to too high intensity levels!
You can extend the range to 105 dB (120 dB in Contra). If you do, a
warning will appear on the screen, and the test screen will visually
indicate that you are using extended range!
Start (dB)
Select the desired start level (from 40 to 110 dB).
Increment (dB)

HBN.
Verification
Verification
Select the type of verification strategy to be used after the deflection
criterion has been met by the automatic threshold search.
The stimulus may be retested for reproducibility, or the next one or
two intensity levels can be used to confirm the reflex growth prop-
erties.
