When should I recalibrate the interactive pens?

You should recalibrate if you notice any of the following while using the pens:

• The pens are difficult to use or respond too slowly.
• The pen's position is not the same as the cursor.
• You can't make selections with the pens, or the pens don't respond.

You should also recalibrate if you move the projector or adjust the image shape using the digital correction settings.
