One or more laser switches are open.

Note: The error message includes the SW number (and description) of the laser safety switch that has been triggered.

1. Resolve the cause why the laser safety switch is triggered.

   • Check if all projector inner covers are installed properly.

   • Check if the laser safety switch is not damaged. If so, replace the switch.

   • Check if the wires of the laser safety switch is not damaged. If so, repair the wires.

   See illustration image and image to know where the laser safety switch is approximately located. The numbers on the illustration correspond with the number of the switch (e.g. SW1=1, SW2=2, etc). The other illustrations show the locations of the laser safety switches more in detail.

2. Clear the laser safety switch error(s) by switching the beam enable key (Master key) off and on. This action will reset the safety controller and erase all safety switch errors.
