Control
L
Select Jump to 1 kHz by output change if you want to default to 1000 Hz when changing ear side.
M
At Jump Strategy you define how the system automatically changes frequency when storing
thresholds.
Bottom makes the cursor start at 1 kHz and move upwards in frequency as the thresholds are
stored. After testing the high frequencies, the cursor will move back to re-test 1kHz and then move
downwards. When jumping back to 1 kHz, the Butterfly strategy can be set to start the re-test at
either the default start intensity or the intensity of the first threshold.
Butterfly makes the cursor start at 1 kHz and move upwards. When the high frequencies have been
tested, the cursor will jump to the lowest test frequency and move upwards towards 1kHz.
None will cause no change when pressing store. The change is carried out manually using the
hardkeys frequency up/down.
N
Butterfly center freq. HL sets the intensity that is used when jumping to the butterfly center
frequency after storing a point at highest or lowest frequency.
O
Intensity decrease when changing freq. sets the number of decibels by which the intensity must
decrease when jumping to the next frequency after storing a threshold.
P
Warble frequency adjusts the frequency modulation of the warble tone from 0-25 Hz.
Q
Warble intensity adjusts the intensity modulation of the warble tone from 0-25%.
Frequencies
R
Enable or disable the frequencies required for the pure tone audiometry assessment.
In addition, the following buttons are available in the tone settings:
