No Signal
The message "No signal" occurs when there is no source signal detected at the
selected input—both HSYNC and VSYNC are inactive and the screen background is
black. Connect or correct the signal, or try another input.
Bad Sync
The message "Bad Sync" occurs when HSYNC or VSYNC are active but the signal
cannot be displayed. Such a condition occurs when only one of the two sync signals
is present, or when either sync signal is unstable or of the wrong frequency. Correct
the signal or select another input.
Other Signal Error Messages
In addition to the common "Bad Sync" and "No Signal" errors, you may encounter a
signal error message indicating that HSYNC and/or VSYNC are either too fast or too
slow. When such a message appears, check the frequencies shown in the Status
menu. If they are correct, then the projector does not recognize the signal. On some
PCs you may be able to change the settings to generate a compatible signal. If the
frequencies shown in the Status menu are incorrect, check the cabling to see where
the problem might originate.
When the projector encounters a system malfunction, either a System Warning
message or a System Error message may appear. Both types of messages are
accompanied by a numerical error code on the "Status" LED, and a related text
message appears in the LCD Status Display window. A system malfunction can be
cleared with from presentation level, but may indicate the need for service

and disappears when the input signal status changes. While the projector will remain
operational, the message indicates the presence of a potentially serious problem that
should be reported to the manufacturer. You can press
