Securing the projector
Using a security cable lock
The projector has to be installed in a safe place to prevent stealing. If not, purchase a lock,
like Kensington lock, to secure the projector. You can locate a Kensington lock slot on the
rear side of the projector. See item 26 on page
11 for details.
A Kensington security cable lock is usually the combination of key(s) and lock. Refer to the
lock’s documentation about 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. Once the password is set and this function is selected, the projector is
password-protected. Users who do not know the correct password can not use the projector.
You will be inconvenienced if you activate the password 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.
