Connecting
Before connecting
f Before connecting, carefully read the operating instructions for the external device to be connected.
f Turn off the power switch of the devices before connecting cables.
f Take note of the following points before connecting the cables. Failure to do so may result in malfunctions.
g When connecting a cable to the projector or an external device connected to the projector, touch any nearby
metallic objects to eliminate static electricity from your body before performing work.
g Do not use unnecessarily long cables to connect to the projector or a device connected to the projector. The
longer the cable, the more it is susceptible to noise. Since using a cable while it is wound makes it act like an
antenna, it is more susceptible to noise.
g When connecting cables, connect GND rst, then insert the connecting terminal of the connecting device
straightly.
f 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.
f Video signals from the video devices 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.
f The projector supports VIDEO signals, YC

signals, analog RGB signals (synchronous signals are TTL
level), and digital signal.
f Some computer models or graphics cards are not compatible with the projector.
f When using long cables to connect each equipment to the projector, there is a possibility that the image will not
be output correctly unless a cable compensator is used.
f For details on what video signals the projector supports, refer to “List of compatible signals”. (Æ page 126)
