Navigation Controls
The four navigation buttons and the middle select button may be used to make
selections from the on-screen menus as well as navigate through the internal
.Wav files for speech testing. The center button when pressed enables the
selection.
Scorer / Timer
The Correct, Clear and Incorrect pushbuttons are used for scoring Speech
test results. The scorer is displayed in the test status area of the Status
screen. When Speech is selected, the scorer initializes to 0/0 = 0%. The
operator presses the Correct or Incorrect pushbutton after each
presentation to score the evaluation. The display resets when the Clear
pushbutton is pressed.
NOTE
: In Pure Tone testing, if the Incorrect/Stop button is pressed instead of
the Store button the No Response (NR) symbol is stored and displayed on the
current frequency and hearing level on the audiogram.
Monitoring
Channel 1 (CH 1), Channel 2 (CH 2), Talkback Controls
The Monitor Headset allows the operator to listen to the stimuli as they are
presented and to listen to the patient’s comments through the talk-back system.
Adjust the Channel 1 (CH 1) and Channel 2 (CH 2) signals by using the select
button to choose the appropriate signal to be adjusted and pressing the push
buttons to the desired hearing level for the operator. Select Talkback to adjust the
level of the patient’s voice for the operator.
When Mic is selected, or when the Talk Forward is operated, that channel’s input
to the monitor speaker is disabled to reduce acoustic feedback.
Test Type Buttons
Test Type buttons allow the operator to transition between audiometric
evaluation components with a single button press. Pressing a test type button
loads all stimuli, routing and transducer preferences from default settings or from
customized protocols determined in the Config App. Transducer and routing are
maintained between test types when allowed. Test types are pre-programmed to
optimize efficiency and workflow.
