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.
