The projector has to be installed in a safe place to prevent theft. Otherwise, purchase a 

lock, such as the Kensington lock, to secure the projector. You can locate a Kensington 

lock slot on the rear side of the projector. See item 25 on page

A Kensington security cable lock is usually a combination of key(s) and the lock. Refer to 

the lock’s documentation for finding out how to use it.
