My Beocenter 2300/2500 doors are slow to open.
There is some tape over the IR receivers designed to make the doors less sensitive.
Simply removing this will cure the problem! It was placed there as the doors were thought to be over-sensitive when first introduced. The tape is in position 9001 and 9019 (Refer to service manual!)
