Adjust the iris to "Open" side.
• This may be interference fringes between dots of printed matter

screen. This may be mitigated by manually adjusting the dot clock
frequency on the projector side (refer to P. 16).

If this machine which is set to PAL is connected to the monitor
specially designed for NTSC, the video image may not be output
