Installing a Security Cable
You can install two types of security cables on the projector to deter theft.
• Use the security slot on the projector to attach a Kensington lock. See your local computer or
electronics dealer for purchase information.
• Use the security cable attachment point on the projector to attach a wire cable and secure it to a room
fixture or heavy furniture.
Note: Do not pass drop-prevention cables through the security cable attachment point when mounting
the projector on a wall or ceiling.
