The optional accessory Digital Interface Box (ET-YFB100G) and Extron's XTP transmitter are only matched 
for this projector. For twisted-pair-cable transmitter of other manufacturers of which the\
 operation has been 
verified with the DIGITAL LINK compatible projector, refer to Panasonic website (http://panasonic.net/avc/
projector/). Note that the verification for devices of other manufacturers has been made for the items set 
by Panasonic Corporation, and not all the operations have been verified. For operation or performance 
problems caused by the devices of other manufacturers, contact the respe\
ctive manufacturers.
This is an average value. It may differ depending on individual product.*5 :
