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

• Make sure Sleep Mode is turned on in the Extended menu Operation settings (sleep mode is turned off by default). See Customizing Power and Operation.
  
  The projector enters sleep mode only if it does not receive a signal for 30 minutes or when the A/V mute slide (lens cover) is closed. If a computer or monitor is connected with the power on, a signal is present and the projector will not go into sleep mode.
