the Power button. This function allows the projector to quickly power off
with an accelerated fan speed. Slightly higher acoustic noise is expected
during quick power off.
NOTE: Before you turn on the projector again, wait for 60 seconds to
allow the internal temperature to stabilize. The projector will take a
longer time to turn on if you try to power on immediately. Its cooling fan
will run at full speed for about 30 seconds to stabilize the internal
temperature.

before switching to power saving mode. Press any button during the
countdown period to stop the power-saving mode.
You can also set a different delay period to enter power saving mode. The

signal. Power saving can be set to 30, 60, 90, or 120 minutes.
If an input signal is not detected during the delay period, the projector
turns off. To turn on the projector press the Power button.
