AT235 Additional Information
H Select Jump to 1kHz by output change if you wish to default to 1000Hz when changing ear side.
At Jump Strategy you define how the system automatically changes frequency when storing
I
thresholds. Bottom makes you rotate through frequencies from bottom up. Butterfly makes you
start at 1000Hz, move up to the highest frequency, jump back to 1000Hz and move down to the
lowest frequency. None results in not changing frequency when pressing store.
Butterfly center freq. HL sets the intensity that is used when jumping to the butterfly center
J
frequency after storing a point at the highest or lowest frequency.
K Intensity decrease when changing freq. sets how many decibels the intensity must decrease
when jumping to the next frequency after storing a threshold.
L At Frequencies you can indicate which frequencies are selectable during audiometric testing.

B The On time sets how long each presentation takes.
The time in between presentations is 2 seconds plus a Random off time. Here you set how much
C
time is maximally added to the 2 seconds.
At Frequencies you can indicate which frequencies are used for automatic audiometry.
