Notice (when edge blending)
• To avoid the image shaking or some pixels in the display may be misaligned, do not use the
projector in the following location:
• In a building close to a construction site.
• In a room where an air conditioner unit is working and it vibrates.
• In a place where the temperature changes dramatically that may cause thermal contraction.
• Before making any adjustment, leave the projector lit for at least 45 minutes after its light
source is turned on. This allows he internal temperature of the projector to stabilize.
