   • While zoomed in on an image, drag the blue square (on the comparison image on the Images for tooth range panel) or the yellow square (on the image under Image Navigator) to pan to another part of the image.

7. Linking the images being compared allows the zooming and panning of one image to be synchronized with the other. To link images, complete the following:

   Now, as you zoom in and out and pan, both images are affected.

   

   Tip: To unlink the images, clicktap the Link icon.
