Informational Notice: IN553x Dual Lamp Model Design - Changing Lamp Configuration
Issue: Lamp Prism movement (prism motor noise) on power up after changing lamp configuration.
Cause: This can occur if the lamp configuration has been changed then the projector immediately shut down. The prism requires approximately two minutes to fully engage itself into the new requested configuration.
Solution: When switching lamp configurations (dual to single, single to dual, or lamp 1 lamp 2), always wait a full two minutes to ensure the prism movement is complete and set.
