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 10 on page 9 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.
Removing the control keypad on the projector
The control key pad on the projector is detachable.
Once the key pad is removed from the projector, it
is not possible to operate the projector without the
control keypad or remote control. We would
suggest that you keep the control key pad and
remote control away from the projector in case they
are taken together with the projector.
To remove the control keypad:
1. Locate the screw locations on the lower
corner of the control keypad.
2. Completely loosen the screws.
3. Lift the control key pad by pulling the screws.
4. Remove the control key pad from the
projector.
5. After removing the control keypad from the
projector, you can use the soft cover supplied
to cover the keypad socket if necessary.
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 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.
