powering the unit o, either download the acquired test reports onto a PC or print out the test reports via
the built-in thermal printer (2) or through a .pdf report creation.
Storage of test parameter settings
Press the TEST MANAGEMENT softkey to access the PARAMETER SETTINGS (5) softkey. Pressing this key will
store the input, output, frequency side and levels being used for the test that is currently underway. The
same parameter settings will be automatically maintained each time the same test is accessed.
Storage shall be subject to acceptance by the operator, to be conrmed via the ENTER key (7).
Patient-Operator Communication
The operator can communicate with the patient either via a built-in microphone (3) or via a headset
integrating the operator microphone, which is connected up to the appropriate connector located
on the unit’s rear panel (28). Once the headset microphone is connected via the rear panel, the built-in
microphone is excluded. The patient will be able to hear the operator via the transducers used for test
performance (headphones, bone conductor, speakers). For operator-to-patient communication, press on
the T. OVER (18) key, for level adjustment, use the CH1 or CH2 (4) adjustment knobs.
The patient speaks to the operator over the patient microphone that is connected to the unit via the rear
panel (27). The operator hears the patient either via the built-in monitor speakers or via monitor-headset,
which is connected to the appropriate connector located on the unit’s rear panel (29). Once the monitor-
headset is connected via the rear panel, the built-in speaker is excluded.
The operator microphone, the patient microphone and the monitor-headset volume levels can be adjusted
by selecting the CONTROLS (17) key which enables access to the controls page. Selection and adjustment is
performed via the arrow keys (10) or the adjustment knobs (4) for both channels.
Monitor Function
The operator can listen to the signals transmitted to the patient either via the monitor-speakers built into
the unit or via a monitor-headset connected to the unit’s rear panel. The monitor is activated or deactivated
via the controls page, by selecting the MONITOR softkey (F4). The control page is accessed by pressing the
CONTROLS (17) key.
Speech Audiometry
Speech material threshold regulation
The test can be performed using speech material from the following sources:
A CD-player connected to the unit (EXT1 and EXT2 inputs); an operator microphone connected to the
appropriate connector on the unit’s rear panel, SD card storing speech material supplied with the unit and
connected into the appropriate slot on the unit’s rear panel (35).
For adjustment of the external signal levels (EXT1 and EXT2) coming either from the CD-player or from the
operator microphone: connect the external signal source to the CD TAPE connectors on the rear panel (26).
From the test page, switch both channels (11) to ON.
Via the INPUT (9) keys, select EXT1 and EXT2.
Press the CONTROLS (17) key to access the controls page.
Proceed with playing the CD track with the calibration signal.
Using the adjustment knobs (4) for both channels, adjust the level of the two EXTERNAL GAIN bars until the
two bar graphs alongside the two adjustment bars, read 0dB.
Press the SAVE (5) softkey to store the level then press GO BACK (5), to return to the test page.
Level adjustment of the speech material provided on the SD card does not require any further adjustments
by the operator. By the keys INPUT (9) and SIDE (8) of the two channels, it is possible to send the masking
noise and the speech material in the same ear in order to perform a Speech in Noise test.
Test conduction and percentage answers
Using the operator microphone or an external signal source (via MIKE or the EXT1 and 2 inputs), the
operator rst needs to set the number of words to be transmitted to the patient, by acting on left and right
(10) arrow keys. Once the phoneme has been conveyed to the patient, the correct reply shall be transmitted
to the program by pressing on the up (10) arrow key. The percentage is detected automatically. The relative
audiogram plotting is generated by pressing the STORE (20) key.
With integrated SD card speech material (SD CARD input), the available speech material play lists and
speech material genres are shown on display. Using the arrow keys (10) it is possible to select the speech
