Installing a projection lens

The projection lens, shipped separately from the projector, must be installed prior to setting up the
projector.
Notice. If not avoided, the following could result in property damage.
• Always use a lens plug when installing or moving the product. This prevents contaminants from
entering the product.
• Do not insert the lens into the product at an angle. This can damage the lens and the optical
components inside the product.
• Always place the lens cap onto the lens when moving the projector to avoid scratching the lens.
• Remove the lens cap before turning the product on to avoid damaging the lens.
