If the password is entered incorrectly three times in succession, the projector's operation is locked. To try again, the user needs to disconnect the projector and reconnect it. If an incorrect password is entered nine times in a row, the projector is locked and remains locked until an authorized person at EPSON can unlock it. You can also create a user's logo for the projector, to be displayed as the startup screen and/or AV/Mute screen. Unauthorized users cannot turn it off or change it. This feature discourages theft and provides a way to identify the projector should it be stolen. Additionally, to make sure a borrowed projector is returned, you can temporarily disable the password for a set period of time. When that time has elapsed, the password function is reactivated and the password must be entered before the projector can be used. Follow the instructions below to first set the password, and then turn on the password and/or user logo protection. [. . . ] If the projector has been on, allow it to cool down for at least half an hour (or until the lamp is cool). Warning Let the lamp cool before replacing it. If the lamp breaks, handle the shards carefully to avoid injury. Turn the projector upside-down to access the lamp compartment. [. . . ]
