3. Setting Up Your Projector
Preventing the lens unit from falling
When suspending the projector, from the ceiling or otherwise, use commercially available wire rope and an attach-
ment to secure the lens unit. In this case, allow about 20 mm of exure of the wire rope for the lens shifting range.
• Recommended wire: Rope diameter 3.0 mm
• Place the wire around the lens unit and the projector’s handle, then tighten it with the attachment to fasten it in place.
