Projector Adjustment and Connecting
3-3. Turning your Projector On
NOTE
• Do not use the projector with the lens cap left attached, and do not attach the lens cap while the projector is
operating. The lens cap may become hot, causing them to deform or melt.
• In the following instances, the power to your projector cannot be turned on even if you press the POWER
button.
- When the inside temperature is abnormally high. The protective function prevents power from turning on.
Wait some time (until the projector inside cools down) and then turn on the power.
- When the SYSTEM status indicator is blinking red without the light source lighting up after power-on. Your
projector may be in trouble. Check the error display on the LCD screen and contact your dealer/distributor
for instructions.
Preparation:
• Connect the power cable to the projector.
• Supply AC power to the projector.
