Obtaining a preferred projected image size
The projected image size is determined by the distance from the projector lens to the 
screen and the video format.
Projection dimensions
Use the illustration and the table below to help you determine the projection distance.
The screen aspect ratio is 16:9 and the projected picture is in 16:9 aspect ratio.
All measurements are approximate and may vary from the actual sizes. If you want a permanent 
installation of the projector, we recommend that you use the actual projector to physically test 
the projection size, distance, and the projector’s optical characteristics prior to the installation. 
This helps you determine the exact mounting position which best suits your installation.

Connection
Connecting the power
1. Insert one end of the supplied power cord into the AC power jack.
2. Insert the plug of the power cord into a power outlet. The POWER indicator on the 
projector lights up in orange after power has been applied.
• Please use the supplied power cord to avoid possible dangers such as electric shock and fire.
• Power systems and plug types may vary depending on your country/region.
Connecting video source devices
You need only connect the projector to a video source device using just one of the 
connecting methods. Each video source provides different picture quality. The method you 
choose most likely depends upon the availability of matching terminals on both the 
projector and the video source device as described below:
If the selected video image is not displayed after the projector is turned on and the correct video 
source has been selected, check that the video source device is turned on and operating 
correctly. Also, check and confirm that the signal cables have been connected correctly.

Connecting a computer
The projector provides a VGA (D-Sub) input socket that allows you to connect it to both 
IBM® compatibles and Macintosh® computers. A Mac adapter is needed if you are 
connecting legacy version Macintosh computers.
To connect the projector to a notebook or desktop computer:
• Using a VGA cable
1. Take the supplied VGA cable and connect one end to the D-Sub output socket of the 
computer.
2. Connect the other end of the VGA cable to the PC socket on the projector.
3. If you wish to make use of the projector’s built-in speakers, take a suitable audio cable 
and connect one end of the cable to the audio output socket of the computer, and the 
other end to the audio input socket on the projector.
Many notebooks do not turn on their external video ports when connected to a projector. 
Usually a key combination like FN + F3 or CRT/LCD key turns the external display on/off. Locate 
a function key labeled CRT/LCD or a function key with a monitor symbol on the notebook. Press 
FN and the labeled function key simultaneously. Refer to your notebook’s documentation to find 
your notebook’s key combination.

Connecting an HDMI source device
The projector provides an HDMI input jack that allows you to connect it to an HDMI 
source device like a Blu-ray player, a DTV tuner or a display.
HDMI (High-Definition Multimedia Interface) supports uncompressed video data 
transmission between compatible devices like DTV tuners or Blu-ray players, and transmits 
signal over a single cable. It provides pure digital viewing and listening experience.
Examine your video source device to determine if it has a set of unused HDMI output jacks 
available:
• If so, you can continue with this procedure.
• If not, you will need to reassess which method you can use to connect to the device.
To connect the projector to an HDMI source device:
1. Take an HDMI cable and connect one end to the HDMI output port of the HDMI 
source device.
2. Connect the other end of the HDMI cable to an HDMI input port on the projector.
The Apple Digital AV Adapter can be purchased from www.apple.com.
