Caution for installation

If the projector and lens were purchased separately, remove the anti-dust cap before use and
store it for future use. When transporting the projector, move the lens to the home position,
remove the lens, and attach the anti-dust cap.

When the projector is not in use, attach the lens cover supplied with the projector or the
projection lens.

Focus adjustment
The high clarity projection lens is thermally affected by the light from the bulb; thus, the focus
is unstable for a short period immediately after the power is turned on. Please wait at least 15
minutes of continuous projection before adjusting the focus.
