NOTE:
B
If the video signal source is connected using a cable with a BNC connector plug, use a
BNC/RCA adapter (sold separately) to convert the cable end to an RCA plug-type jack.
BIf the signal cables are disconnected or if the power supply for the
computer or video deck is turned off while the digital zoom or index
window functions are being used, these functions will be cancelled.

Notes on connections

B
Read the instruction manual for each system component carefully before connecting it.
B
Turn off the power supply for all components before making any connections.
B
If the cables necessary for connecting a component to the system are not included with the component
or available as an option, you may need to fashion a cable to suit the component concerned.
B
If there is a lot of jitter in the video signal which is input from the video source, the picture on the
screen may flicker. In such cases, it will be necessary to connect a TBC (time base corrector).
BRefer to the list on page 58 for details on compatible signals which can be
input to the projector.
B
Only one audio system circuit is available for the AUDIO IN L-R jacks, so if you wish to
change the audio input source, you will need to remove and insert the appropriate plugs.
