Raise the Thoracic cushion as high as it will go. Look for the drive below the thoracic area. The red letters or numbers in the LED window indicate the drive status.
To access the drive you will need to remove the plastic enclosure from around the top frame. Use the pedal to elevate the table. Unplug the table. There are two screws at the head end, near the arm rests, two screws at the foot end of the plastic, and one on each side. Pull the plastic down and away to free it from the arm rests if you want maximum visibility.
