Set the desired volume level with the Down-key
Ì
respectively the Up-key
Î
. On the LCD display
Ç
below the left reflex box at the bottom the
selected level in dB appears. The starting level is always 80 dB.
If you like to change the test frequency from the default 1 kHz use the Left-
key
Ë
respectively the Right-key
Í
. On the LCD display
Ç
below the reflex
boxes at the bottom below the selected level in dB, the test frequency
appears.
The pressure will automatically be set at the peak pressure for maximal
compliance.
Instruct the patient not to talk, swallow, yawn or move until the test is over.
Any movement or sound will give unreliable results.
Press the ENTER button
Ï
when ready to run the test.
Watch the probe LEDs for an indication of test operation. See chapter 3.6
for an explanation of the
LEDs.
An individual whose
peak amplitude decays
50% within the 10
second time limit shows
signs of adaptation, or
decay. The percentage
value is displayed after
10 seconds.
In figure 26 test result is
shown. The emphasized
black bar below the 0 ml
line indicates the
duration of the test
stimulus.
To save the result and or / perform an additional test press the
DECAY
key
Ñ
. On the LCD display
Ç
in the left reflex box at the bottom the last result
is now shown.
The next right test box is now highlighted. You can do now a test with
different level or frequency. Select it as described before.
