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 20 on page
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.
Utilizing the password function
For security purposes and to help prevent unauthorized use, the projector includes an
option for setting up password security. The password can be set through the On-
Screen Display (OSD) menu.
WARNING: You will be inconvenienced if you activate the power-on lock
functionality and subsequently forget the password. Print out this manual (if
necessary) and write the password you used in this manual, and keep the manual in
a safe place for later recall.
