Locking control keys With the control keys on the projector locked, you can prevent your projector settings from being changed accidentally (by children, for example). When the Panel Key Lock is On, no control keys on the projector will operate except Power. 1. Press Lock on the remote control for 3 seconds. Press Lock on the remote control, a confirmation message "Are you sure to lock panel keys?" is displayed. Select Yes to confirm. To release panel key lock: 1. Press Lock on the remote control directly. The Panel keys are unlock. Important • If you press Power to turn off the projector without disabling panel key lock, the projector will still be in locked status the next time it is turned on. • Keys on the remote control are still functional when panel key lock is enabled. 24
