ConnectingBefore connectingf 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.- When connecting a cable to a device connected to the projector or the projector itself, touch any nearby metallic objects toeliminate static electricity from your body before performing work.- Do not use unnecessarily long cables to connect to a device connected to the projector or to the projector body. The longerthe cable, the more it is susceptible to noise. Since using a cable while it is wound makes it act like an antenna, it is moresusceptible to noise.- When connecting cables, connect GND first, then insert the connecting terminal of the connecting device in a straightmanner.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, atime base corrector (TBC) must be connected.f The projector accepts VIDEO signals, Y/C signals, YCBCR/YPBPR signals and analog RGB signals (synchronous signals areTTL 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 beoutput correctly unless a compensator is used.f For details on what video signals the projector supports, see “List of compatible signals”.
