Something wrong with the pump of Beckman Avanti J-E

We have a Beckman Avanti J-E made in 2017.  We kept the fuge in storage for one year.  Last week, I tried to turn on the fuge and found it spined fine without any issue.  But I noticed the vac pump kept working for all the 30 min running time.  It seems it is not used to be like this.  I understand when the vac level reaches to a certain number, the pump shall stop.  The thing is how we can set up the vacuum value and let the pump stop when vac reaching the level.  Also how can we check the vac level when the fuge is running.  Are there buttons we can hit to display the vacuum level?  Thank you.
