full display of the dust drawer should be set to 5 hours, if necessary, 10 hours.
5.4.3 Swtich-on Theshold for Automatic Operation
⇒ On delivery, the switch-on thresholds are provided for the two suction channels, which enable trou-
ble-free operation with most handpieces�
⇒ If the suction function does not react correctly to a connected handpiece, the switch-on threshold can
be set individually for each suction channel�
⇒ Press the Menu key (20) 4 x�
♦ The symbol - set switch-on threshold - (24) blinks�
♦ The letters A and B blink�
⇒ Press the suction key (29) of the suction channel which is to be set�
♦ The letter of the selected suction channel is displayed�
♦ The display shows “OFF”�
⇒ Switch this off in an electrical device without standby mode
⇒ In an electrical device with a standby mode (e�g� handpieces), switch to standby mode (e�g� with a
handpiece, switch only the control unit on without activating the handpiece)�
⇒ Press the Enter key (30)�
♦ The display shows “ON”�
⇒ Switch this on in an electrical device without standby mode
⇒ For handpieces, operate this at the speed at which the suction is to be started and run for approx�
3 - 5 seconds (so that overflow during start-up is not detected).
⇒ Press the Enter key (30) (whilst the handpiece is still running)�
♦ The setting is saved�
⇒ Select the next suction channel to be set or exit with the Menu key (20)�
For devices with standby mode, these should be switched on approx. 5 minutes before setting to
avoid incorrect measurements.
If an error occurs during the setting of the switch-on threshold, the display will show “Cal” and an
acoustic signal will sound 2 x. Set the changes again.
5.4.4 After-run Time of the Suction Turbine
After-run time = The period of time between switching a connected device off and the closing of the corre-
sponding suction channel (= pinch valve)�
A distinction is made between three after-run times, which can be set independently of one another:
• After-run time suction channel A

only suction channel A is open:
Time, until the pinch valve of suction channel A closes and the suction turbine switches off�
• After-run time suction channel B

only suction channel B is open:
Time, until the pinch valve of suction channel B closes and the suction turbine switches off�
• After-run time suction channel A and B

both suction channels, A AND B, are open:
Time, until the pinch valve of a suction channel closes and the suction performance for the other suction
channel is adjusted�
