About this task

The cradle is locked in home position on the Fixed Table by a latch in the cradle, which engages a notch in the cradle guide strip near the end of the Fixed table. The cradle should be able to just engage this notch, without extra force, when pushed to home position on the table top, yet it must engage it tight enough so the table top (cradle) will not move on the Patient table freely when it is not engaged with LPCA.
