knob.
3.Replace the filter cover for bottom-up use and snap it back into place.
4.Slowly turn up the projector so that the top is facing up.

is connected to a power supply or is in a high temperature state, handling the projector
could cause electric shock, a fire, a burn and/or malfunction to the projector.
Before handling, make sure the power switch is off and the power cord is not plugged in,
then wait at least 45 minutes.
