Figure 4. Display of Threshold
The threshold may be cleared (Clr) by pressing key {4} (e.g., to retest a threshold).
Only the currently-displayed threshold will be cleared.
The test ear, signal mode, starting frequency and starting level are all user
selectable, so these values may differ from the ones shown. The example shown
indicates that threshold of 20 dB has been obtained for the right ear at 1000 Hz.

Table 2 lists the functions of ES3 keys that are active in the manual audiometry
