• Panel Key Lock
With the control keys on the projector and remote control 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
and remote control will operate except POWER.
To release panel key lock, press and hold (the right key) on the projector or
remote control for 3 seconds.
If you turn off the projector without disabling panel key lock, the projector will still be in locked
status the next time it is turned on.
