⇒ 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.

is emitted twice.
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 suc-
tion channel is adjusted�
In order to prevent the suction from being switched on / off too often, or the suction performance
to be adjusted too frequently in the case of short interruptions (for example when working with
the handpiece), a higher time value should be selected.
