If the projector is used with a screen size not listed in this manual, check the diagonal dimension (inch) of your
screen and calculate the projection distance using the following formulas.

Connection
Before connection, read carefully the instruction manual for the device to be connected.
Turning off the power switch of the devices before connecting cables.
If any connection cable is not supplied with the device, or if no optional cable is available for connection of the
device, prepare a necessary system connection cable to suit the device.
Video signals containing too much jitter may cause the images on the screen to randomly wobble or wafture.  In
this case, a time base corrector (TBC) must be connected.
The projector accepts the following signals: video, S-Video, analog RGB and digital signals from the PC.
Some PC models cannot be connected to the projector.
The pin-out and signal names of the S-VIDEO IN terminal are shown in the diagram below.
The pin-out and signal names of the RGB2 input terminal are shown in the diagram below.

Example of connecting with VIDEO devices
• When connecting with a video deck, be sure to use the one with a built-in time base corrector (TBC) or
use a TBC between the projector and the video deck.
• If nonstandard burst signals are connected, the image may be distorted.  If this is the case, connect a
TBC between the projector and the video deck.Attention

Note
• When multiple signals of the same type are switched and input to RGB1 IN (for example, when
switching multiple high-vision signals for usage), use a dedicated signal selector. When the signal
selector is connected to the projector with a RS-232C cable, signals can be used separately
according to the input terminal on the signal selector.
• Carefully read also the instruction manual for the signal selector.
