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 17 on page 9 for details.
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.

option for setting up password security. The password can be set through the On-Screen

password. Print out this manual (if necessary) and write the password you used in this manual, and keep the
