Note: Along with the message, you will also see an indicator like this. Projector 1 represents the
commander and projector 2 represents the receiver. The green arrow points to the projector that the
message is referring to.
You can replace the air filter while the projector is mounted to the ceiling, if necessary. The illustrations
here show the projector placed on a table.
Note: The illustrations in this section show how to replace the commander projector's air filter, but you
can replace the receiver projector's air filter using the same steps.
1. Turn off the product and unplug the power cords.
