The product won't go into sleep mode. What should I do?

• Make sure Sleep Mode is turned on in the Extended menu (sleep mode is turned off by default), and that the Sleep Mode Time setting is set to the desired length of time you want before the projector turns off automatically. See Extended Menu.
  
  The projector enters sleep mode only if it does not receive a signal for the period of time specified in the Sleep Mode Time setting. If a computer or monitor is connected with the power on, a signal is present and the projector will not go into sleep mode.
