play a single frequency warble tone. Once clicked, the
exact frequency, input and output can be seen on the
graph. The frequency can be adjusted up and down
by using the Right and Left arrows on the keyboard.

UCL (Uncomfortable Levels) Adjustment
To limit the system's signal intensity while measuring the MPO during a
Real-Ear situation, the UCL button can be activated. Once activated, a
red line will appear on the graph and the system will stop measuring if
this UCL level is reached. This red line can be adjusted with the slider.
NOTE: UCL thresholds must be entered on the audiogram for the red
line to appear when the UCL button is active. To deactivate this
feature, press on the UCL button again.
