  If your Weinmann Medical Equipment exhibits no running noise and the display is blank, the issue might stem from a lack of supply voltage. To resolve this, ensure the connecting cord is securely connected. You can also verify the functionality of the supply socket by plugging in another device, such as a lamp.

  If the display on your Weinmann Medical Equipment has gone out, it could be due to a couple of reasons. First, check that the connecting cord is securely connected and test the supply socket with another device like a lamp to ensure there is supply voltage. Alternatively, if you are using a VENTIpower battery, it may have discharged. In this case, disconnect the VENTIpower from the VENTIlogic and recharge it. You can continue operating the VENTIlogic via a supply socket while the battery recharges.
