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
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
NOTE: System messages appear
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 Exit 
to remove the message, but for best results you should reset the 
key.
