OPERATION
No Signal
The message "No signal" appears when there is no signal detected at the selected input. Both
HSYNC and VSYNC are inactive and the screen background is black. Connect or correct the sig-
nal, or select another input.
On the IR remote or wired keypad, press to display the projector box. Press again without enter-
ing a number - the keypad commands will now affect all projectors.
Make certain that only one projector has its "Broadcast Keys" option selected (checked) - the
remaining projectors should have the option unchecked and their keypads disabled (do this in
Preferences menu). The "Broadcast Keys" projector will then relay keypad commands to the oth-
ers. If using a wired remote, make sure to select the "Broadcast Keys" option for the projector to
which the wired remote is connected.
NOTE: If you are using a computer or controller to issue commands, use the correct RS-232 soft-
ware command to broadcast.
Bad Sync
The message "Bad Sync" is displayed when HSYNC or VSYNC are active but the signal cannot
be displayed. Such a condition occurs when only one of the two signals is present, or when either
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 Information menu. If they are correct, then the sig-
nal may be out of the projector's operating range. On some PCs you may be able to change the
settings to generate a compatible signal. If the frequencies shown in the Information menu are
incorrect, check the cabling to see where the problem is.
System Warnings / Errors
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 steady red
"Power" LED and a flashing red-and-yellow error code on the "Status" LED. This condition indi-
cates the need for service by a qualified Runco service technician.
NOTE: System messages appear on-screen only if Display Error Messages has been set to
"Screen" or "All".
System Warnings
A system warning message indicates that a system malfunction has been detected (see Status LED
Codes, below). A system warning message replaces any input signal message and disappears
when the input signal status changes. While the projector will remain operational, the message
indicates the presence of a serious problem that should be reported to the manufacturer. You can
press to remove the message, but for best results you should reset the projector-power the
projector down and up again with the key.
