It’s recommended to place the Lens caps of the original Lens packaging, back on both sides of the removed
Lens to protect the optics of the Lens.
It’s recommended to place the plastic cover of the original projector packaging, back into the lens opening to
prevent intrusion of dust. This plastic cover prevents that dust is entering the projector.
If no lens is installed the lasers of the Thor series projector can not be powered. The Standby button en Light
button will light up red. The Communicator will also show the error message that there is no lens installed.
