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 a device connected to the projector or the projector itself, 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 a device connected to the projector or to the projector
body. 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 in a
straight manner.
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 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 accepts Video signals, Y/C signals and YC

signals and 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 with each of equipment to the projector, there is a possibility that the image
will not be output correctly unless a compensator is used.
f For details on what video signals the projector supports, see “List of compatible signals”. (x page 129)
