See “Keystone” on page11.  
Caution: The projector requires a warm-up period (approximately 45 seconds) after the power is  
turned on and a cool-down period (approximately 60 seconds) after the power is turned off.  
The power cannot be turned on for at least 1 minute after the unit has been turned off. This is a safety  
feature.
