section of the screen frame, just above the corresponding keys. Said functions will
vary according to the type of test being run or the menu that is displayed.
6. TEST: when in testing mode, this key enables return to the main selection page.
7. ENTER: key for accessing the tests from the main menu.
8. RIGHT – LEFT inputs for channels 1 and 2: in audiometry testing, these keys enable
selection of the ear being tested for both channels. The selected stimulus signal is
thus sent to the transducer corresponding to the selected ear.
9. OUTPUT – INPUT for channels 1 and 2: enables individual selection of the type of
stimulus and the transducer used for testing.
10. ARROW KEYS: used for the various selections provided on the menu pages. For
multifrequency audiometric testing they are used to set and enter the frequency
step and to change the base frequency setting.
11. NORM/REV for channels 1 and 2: in audiometry testing, these keys enable stimulus
transmission to the transducers. Normal mode (output signal present when pressing
SIGNAL key 12). Reverse mode (output signal not present, when pressing SIGNAL key.
12. SIGNAL for channels 1 and 2 (touch keys): in audiometry testing, with the channel
in normal mode, these keys enable transmission of the respective channel signals
to the transducers for the length of time they are pressed. In Reverse mode,
these keys deactivate the transducer output signal for the length of time they are
pressed. During tympanometry tests, manual start of refl ex tests is enabled (via
CH1) and, once the function is enabled, manual pressure can be reset (via CH2).
13. FREQUENCY: both for audiometry and for tympanometry tests, keys enable
selection of the signal frequency sent to the transducers.
14. IPSI: in middle-ear analyzer tests, this key is used to select the probe as a transducer
for the transmission of stimuli during stapedial refl ex detection tests.
15. CONTRA: in middle-ear analyzer tests, this key is used to select the contralateral
transducer for the transmission of stimuli during stapedial refl ex detection tests.
16. SIDE: in middle-ear analyzer tests, this key enables selection of right or left ear.
17. CONTROLS: in audiometry testing, this key provides access to the external signal
adjustment and calibration page, for the monitor-headset, for the patient-to-operator
mike (e.g. for talk back) and for the operator-to-patient mike (e.g. for talk over).
18. T. OVER: in audiometry testing, this provides direct access to the talk over
microphone volume adjustment controls (for operator to patient communication).
19. START/STOP: both in audiometry testing and in tympanometry tests, this key
enables start/stop of some of the test options (for Autothreshold, SISI, Tone Decay,
Bekesy and Speech Audiometry in clinical audiometry testing further to all the
tympanometry test options).
20. STORE: in audiometry testing, this key enables storage and display of the values
measured during audiogram testing.
21. PRINT: if pressed from the main selection page, this key enables printing of all
the tests performed (via thermal printer, or by creating a pdf report), otherwise
printout of a single test is possible if the key is pressed directly from the test page
(with printout via the built-in thermal printer).
