Preventing unauthorized use
You can prevent unauthorized people from using the projector by creating a secret button sequence that is required for the projector to turn on. The unlock sequence is a series of 4 to 8 arrow buttons. If the buttons are not pressed in the order you specify, the projector does not turn on. Use the following steps to set or clear an unlock sequence.
1.Press enter, go to Setup > Advanced setup > Projector lock, and press enter.
2.If an old unlock sequence is set, press the buttons according to the old sequence when prompted, and then press enter.
3.To set a new unlock sequence, press the arrow buttons for the new sequence, and then press enter.
To clear the unlock sequence and remove this protection, press only enter.
4.When prompted, confirm the new sequence and press enter.
NOTE: If you set an unlock sequence, you must press the sequence every time you turn on the projector. The sequence protects the projector only when the projector is turning on, not at any other time.
If you forget the unlock sequence, you must call HP support to unlock the projector. You must have the projector and your proof of purchase.
