I did some more research on these desk (we own 3).
There are some things people don’t know,
1. You can only change x times, before PSU goes in protection mode. It will work again after a while (up to half hour)
2. Resetting the desk is done by holding the down button, which effectively resets desk height system.
3. The desk has a anti injury/stuck protection, which stops and moves the desk one centimeter in opposite travel direction.
@ our office we now control the Bekant desks with our computers, so sitting and standing height follows the logged in user.
