Securing the projector

Using a security cable lock

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 22 on 

page 8

.

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.
