Locking the Projector's Lens Settings and Buttons
You can lock the buttons on the projector's control panel to prevent anyone from using the projector. You
can also lock the zoom, focus, and lens shift settings to prevent them from being adjusted.
Note: You can use the remote control to control the projector when the control panel buttons are locked.
1. Press the Menu button.
2. Select the Management menu and press Enter.
3. Select one of these lock types and press Enter:
• To lock the zoom, focus, and lens shift settings, select Lens Lock.
• To lock the projector's power button, select Child Lock. To turn the projector on, you must press
the power button for longer than three seconds. You must restart the projector to enable this lock
setting.
Note: Child Lock does not prevent the projector from turning on when the power cord is
connected if the Direct Power On setting is enabled in the projector's Operation menu.
