Operating Instructions
Preparing the Patient for Testing
Otoscopic examination of the patient’s ear canals should be
performed prior to testing. Excessive cerumen or vernix in the ear
canals may interfere with the test and give invalid or incomplete
results. Patients with excessive cerumen, debris, or foreign bodies in
the ear canals should be referred to an audiologist or physician for
removal of the blockage prior to testing.
Place the patient in a position that will allow easy access to the ear
canal. The patient should remain still and quiet while the test is being
performed.
Turning On the Instrument
To turn on the Corti instrument, press the DOWN button located
below the instrument’s display screen (Figure 9). The yellow TEST
light will appear briefly just above the display. The green READY
light will remain on indicating the instrument is ready for use. A Flash
Screen will appear briefly, indicating the software version, serial
number, next calibration date, and type of instrument:
SCR Screener with TE or DP

Control Panel
The Corti instrument uses 4 buttons to control all functions of the
instrument (Figure 9). These buttons are arranged in a directional
cursor format. The arrows on the keypad (
LEFT,
RIGHT,
UP,
and
DOWN) correspond to the arrows that are used on the screen.
The screen will indicate which button to push by showing the
appropriate arrow.
NOTE:
The UP key will always bring the instrument back to either
the previous menu or the main menu. The UP key will also access the
print command from the Main Menu.
