Note:
• Using the computer control function of the unit, the liquid crystal projector conditions cannot be read to the computer.
Therefore, confirm the conditions by transmitting the display commands for each adjustment menu and checking the
conditions with the On-Screen Display. If the unit receives a command other than a menu display command, it will execute
the command without displaying the On-Screen Display.
