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

• Make sure Sleep Mode is turned on in the Extended > Operation menu (sleep mode is turned off by default), and that the Sleep Mode Timer setting is set to the desired length of time you want before the projector turns off automatically. See Customizing Power and Operation.
  
  The projector enters sleep mode only if it does not receive a signal for the period of time specified in the Sleep Mode Timer 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.
