Using Basic Projector Features
Monitoring and Controlling the Projector
Clean the projector's obstacle sensor glass periodically, or if you see a message telling you to remove any obstacles that are interfering with the projection area. To remove dust or smudges, gently wipe the sensors with lens-cleaning paper.
WarningDo not use a lens cleaner that contains flammable gas to clean the obstacle sensor. The high heat generated by the projector may cause a fire.
Do not use glass cleaner or any harsh materials to clean the obstacle sensor and do not subject the obstacle sensor to any impacts. Damage on the surface of the sensor may cause malfunctions.
