2. Projecting an Image (Basic Operation)
CAUTION:
Parts of the projector may become temporarily heated if the projector is turned off with the POWER button or if the
AC power supply is disconnected during normal projector operation.
Use caution when picking up the projector.
NOTE:
• While the POWER indicator is blinking blue in short cycles, the power cannot be turned off.
• You cannot turn off the power for 60 seconds immediately after turning it on and displaying an image.
• Wait at least 20 minutes after the power is turned on (after starting to project) before turning the AC power off while an image is
being projected or while the cooling fan is running.
• Do not unplug the power cord from the projector or from the power outlet while an image is being projected. Doing so could
deteriorate the projector’s AC input connector or the power plug’s contact. To turn off the AC power while an image is being
projected, use the projector's main power switch, the power strip’s switch, the breaker, etc.
• Do not disconnect the AC power supply to the projector within 10 seconds of making adjustment or setting changes and closing
the menu. Doing so can cause loss of adjustments and settings.
• Do not turn off the main power using the Main Power Switch or by disconnecting the power to the projector while lens adjust-
ments are being performed. If power is removed while the lens is moving, you may not be able to achieve the best possible lens
adjustments after restarting the projector.
