Note: It is recommended always to make a preceding tympanometry
test in order to establish the correct middle ear pressure which is the
optimal basis for precise reflex test.
If a reflex test is performed without first making a tympanometry
curve, the reflex will be performed at 0 daPa and not at the correct
middle ear pressure.
1.
Select test ear by means of “Right” (19) or “Left” (20).
2. Place the probe in the test ear.
The probe will have an airtight fit when the indication light on the
probe is green. When the status “Leaking” or “Blocked” is displayed
in the upper right hand side of the screen the indication light on the
probe will be yellow. This indicates a bad fitting or a blocked ear tip.
When a correct fit has been obtained the reflex test will begin.
2a) If clinical headset is used:
When using the clinical headset select "Pause" (9) to
prevent the instrument from automatically starting the test
as soon as an airtight fit has been obtained.
Place the clinical headset over the patient's head or use the
shoulder strap and insert the probe tip into the ear canal.
When an airtight fit has been obtained the reflex test is
ready to be performed. To start the test, select "Pause" (9)
once again and the test will be carried out automatically.
Note: From the Common Setup Menu it is possible to set up the
“Pause” key (9) to be controlled from the Remote Switch of the
probe.
On the screen the reflex test can be followed on-line.
3. Remove the probe from the first ear when the test sequence
has finished. Select the other ear “Right” (19) or “Left” (20),
move the probe to the second ear and repeat the test
sequence once again.
