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.
- 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.
- 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.
- When connecting cables, connect GND first, 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.

For details on what video signals the projector supports, see “List of compatible signals”. (
