Using the Viewer function
If you use the Viewer function on the LCD projector, you must
first install the optional MT Viewer board (VK-MT) in the
LCD projector and set up the exclusive software included with
the VK-MT kit.
See the user's manual included with the VK-MT for installing
and uninstalling the software.

1. Set the LCD projector on end with the carrying handle up.
NOTE: Be sure to unplug the LCD projector before installing the Viewer

4. Insert the optional viewer board into the slot. Be sure to
push the board until the board is securely fitted.

removed in step 2.
