If Wave is selected by the speech signal selector (11) or (15) a menu will pop-
up with available word lists, stored on the SD memory card. A word list can be
selected by using the level control (1) to scroll through the list. A list can be
loaded by pressing the stimulus button. The words of the list will be displayed
in the speech audiometry screen.
The level is displayed as a numerical value at the top of the screen. The level
can be changed with the level controls (1) on both sides of the instrument.
Before starting the playback of the wave files, the first word can be selected by
the frequency up and down buttons (4) and (5). Press the functional button

The procedure for the SRT, WRS, MCL and UCL test is the same like for CD or

selected in the wordlist by the frequency up (4) or down (5) key. When the
button Play (7) is pressed, the selected word is presented. Increase or decrease
the level in case of a correct or incorrect response till the SRT is estimated and
store the result by pressing the button Store (3).
For the WRS test tally the correct words by pressing the frequency up (4) key
and the incorrect words by pressing the frequency down (5) key. The next word
will be played back automatically. Press the functional button Pause (7) to
interrupt the play back.
The percentage of the speech discrimination score is displayed and will be
