and the possibility of injury. Maintain at least ±5° of overtravel between the optical
limits and the hard stops.

The following procedure describes how to adjust the optical limits. Refer to
1. Disconnect all electrical power from stage.
2. Remove the [QTY. 3] M3 Flat-Head Screws to remove bottom cover from stage.
