If your Compella bed is equipped with powered drive, you cannot use the scale nor arm the bed exit alarm when the bed is in transport mode. If you attempt to use the scale or bed exit while the powered drive wheel is lowered, the “Raise Bed” indicator light on the control pod will flash and you'll hear a triple-beep alert. To remove the bed from transport mode, press and hold the “Raise Bed” indicator control on the pod. Once the indicator light is off, the scale and bed exit alarm are ready for use.
