The frequency display "7" allows viewing the selected frequency, sequentially from the
decrease button «8» and the increase button "9".
The possible frequency range is as follows:
125 Hz 250 Hz
The sound level display "4" allows viewing the selected level of sound, sequentially from
decrease key "5" and increase key "6", by steps of 5 dB, from -10 dB to 100 dB (the upper
limit depends on the frequency).
When pressing:
 Key "10", the audiometer sends the selected sound (frequency, level, continuous /
pulsed) on the patient's left ear.
 Key "11", the audiometer sends the selected sound (frequency, level, continuous /
pulsed) on the patient's right ear.
The sound lasts as long as key is pressed, unless the hand switch patient response has
been pressed. In this case, the display indicates the patient's response time (in seconds)
between the sound sending time and the time at what the patient pushes on the hand
switch. This information remains visible up to one of the keys "10" or "11" is still pushed
on.
