  Operation

Switching input signal

The projector can be connected to multiple devices at the same time. 
However, it can only display one full screen at a time. When starting up, 
the projector automatically searches for the available signals.
Be sure the 

Advanced Menu - System Setup : Basic

 > 

Auto Source 

 

menu is 

On

 if you want the projector to automatically search for the 

signals.
To select the source:
1.  Press 

SOURCE

. A source selection bar appears. 

2.  Press 

/

 until your desired signal is selected and press 

OK

.

Once detected, the selected source information will appear at the corner of the screen for seconds. 
If there is multiple equipment connected to the projector, repeat steps 1-2 to search for another 
signal.

Shutting down the projector

1.  Press 

 and a confirmation message will appear prompting 

you. If you don't respond in a few seconds, the message will 
disappear.

2.  Press 

 a second time. The power indicator flashes 

orange, the projection lamp shuts down, and the fans will 
continue to run for approximately 90 seconds to cool down 
the projector.

3.  Once the cooling process finishes, the power indicator 

becomes a steady orange and fans stop. Disconnect the 
power cord from the power outlet.

Direct power off

The AC power cord can be pulled out right after the projector is turned off. To protect the lamp, wait 
about 10 minutes before re-starting the projector. If you attempt to re-start the projector, the fans may 
run for a few minutes to cool down. In such cases, press 

 again to start the projector after the fans 

stop and the power indicator turns orange.

• The brightness level of the projected image will change accordingly when you switch between different input 

signals.

• For best display picture results, you should select and use an input signal which outputs at the projector’s native 

resolution. Any other resolutions will be scaled by the projector depending upon the “aspect ratio” setting, 
which may cause some image distortion or loss of picture clarity. See 

Aspect Ratio on page 40

.

• To protect the lamp, the projector will not respond to any commands during the cooling process.
• To shorten the cooling time, you can also activate the Quick cooling function. See 

Quick Cooling on page 42

.

• Avoid turning on the projector immediately after turning it off as excessive heat may shorten lamp life.
• Lamp life results will vary depending on environmental conditions and usage.
