Insert a well-plate holder
First, place the well-plate holder on the FRAME's stage as shown in the below image (with the orientation shown in the below image), and then use your Allen wrench to secure the well-plate holder with one screw at each corner of the well-plate holder:

As we can see in the image above, three corners of the well-plate holder have flat surfaces, while the fourth corner has a small button attached to a spring-loaded mechanism which is secured with four screws. The well-plate holder should be oriented so that the corner with the button is closer to the rear of the FRAME, where the FRAME's illumination arm is mounted; that corner corresponds to your well plate's corner notch (chamfer) at the A1 position.
