Connecting
Before connecting
f
Before connecting, carefully read the operating instructions for the external device to be connected.
f
Turn off the power of all 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 a device to the projector or to the projector body. The longer
the cable, the more susceptible to noise it becomes. 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 first, then insert the connecting terminal of the connecting device in a
straight manner.
f
Acquire any connection cable necessary to connect the external device to the system that is neither supplied
with the device nor available as an option.
f
If video signals from video equipment contain too much jitter, the images on the screen may wobble. In this
case, a time base corrector (TBC) must be connected.
f
If synchronization signals output from computers or video equipment are disrupted due to changes in the video
output setting or other reasons, colors of projected images may be temporarily disrupted.
f
The signal that can be connected to the projector is video signal, YC

signal, analog RGB signal
(synchronization signal is TTL level), and digital signal.
f
Some computer models or graphic cards are not compatible with the projector.
f
Use a cable compensator when you connect devices to the projector using long cables. Otherwise the projector
may not project the image properly.

For details of the types of video signals that can be used with the projector, refer to “List of compatible signals”
