DB: One hand truing not available anymore

If the existing option for one hand truing is no longer selectable in the settings, there are a two things that should be checked.

1. Check in the special menu whether the option is activated.

     If the option is active and still not present in the settings then

2. Check the speed of cylinder for the right nipple hand moving up/down.

     When pressing start on the screen, the machine will pressurize and tries to move the nipple                 hands. If it pressurize too slowly and the hand is not moving, one hand option won't be            b         available.
