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 signal, or select another input.
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 Status
menu. If they are correct, then the signal is not recognized by the projector. 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 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 indicates the need for service by a qualified
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). It 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
Exit
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.
System Errors
A system error message indicates that a serious malfunction has been detected and
must be reported to the manufacturer (see Status LED Codes, below). The projector
will no longer operate and must be reset—power the projector down and up again

with the key.
Status LED Codes
If the "Status" LED on the back of the projector repeatedly flashes a pattern of yellow
and red light while the "Power" LED glows a continuous red, you have encountered a
likely system error requiring the attention of a qualified service technician (see
System Warnings and System Errors, above). Try resetting the projector by powering
it off and on again, cooling when necessary. Consult Table 3.2. System Error Codes
and contact your dealer if the problem persists.
