To initialise, move the desk to the bottom position; to do that, press the down key on the hand-switch until all
drives have reached the lowest position. Press the down key once again and keep it pressed (approx. 5
seconds) until the desk moves slightly down and then back up. Let go of the button only after the desk stops
moving. If you let go of the button too soon, that causes a malfunction on the desk. If this happens by mistake,
you have to repeat the process.
Attention: The top limit stop of the controller is preset. For this reason, use only controllers that
were supplied as suitable for the respective desk base.
Danger: The optionally available corrosion protection is not activated during any reset process.
During this process, always watch out for the possible danger of being crushed.
