LCD projectors can be found in many multi-user environments like schools and businesses. Sometimes you will want to control use. Many LCD projectors have at least one of two ways to block use. They can include a PIN (Personal Identification Number) access feature, or a physical security lock, which will prevent the LCD projector being moved and used somewhere else. Some projectors have both methods. Controlling an LCD projector's use can be accomplished by following some steps.
Instructions
1. Enter the Setup menu. Often the menu can be accessed from a dedicated button on the remote control, or on the projector's case. Sometimes the button is marked "Menu."
2. Scroll through to the "PIN Protect" or similar menu item. Use the navigation buttons to enter the correct sequence of buttons. The default on an InFocus is "Menu," then "Up," then "Down" and then "Select Source." Press the "OK" button and confirm you want to use this code, or choose a new code by entering it. Confirm that you want the projector to ask for a PIN at start-up.
3. Turn the projector off and then on again. The "Enter PIN" dialog box will appear. Use the correct buttons to enter the sequence, and the projector will turn on.
4. Use the security lock, if the projector has one, to attach a cable and padlock. Look for a small slot on the projector marked "Security" or similar. Insert the slotted end of the padlock from the kit. Then attach the cable and wrap the cable around a fixed object like a nearby water pipe.
