Acoustic signal

The acoustic signal sounds:

After a disturbance occurs, in 2 second intervals.

After completion of a centrifugation run and rotor standstill in 30 second intervals.
The acoustic signal is stopped by opening the lid or pressing any key.
The acoustical signal can be activated or deactivated as follows when the rotor is at a standstill:

Switch off the mains switch.

Keep the key beneath the speed indicator and the key

Switch on the mains switch and release the keys again.

Press the key beneath the speed indicator until the following display appears:
RPM x 100 t
The acoustical signal setting is displayed on the time display.
0 = acoustical signal deactivated, 1 = acoustical signal activated.

With the keys below the time display, set 0 or 1.

Press the key to save the setting.
