Invalid User Entry
A keypad entry not recognized by the projector triggers a short on-screen error
message identifying the problem. For example, if you specify a channel number that is
not available, the message “Invalid Channel will appear. Or if you try to enter the
wrong password, you’ll see “Invalid Password”. Press
or
Exit
to clear the
message and try again.
NOTE: On-screen display of “Invalid User Entry” messages cannot be disabled, even
if Display Error Messages has been set to “Off”.
An input signal error message occurs if you are in presentation level (i.e., there are no
menus present) and have selected an input on which the projector detects a problem.
While menus remain operational and any key press will temporarily remove any
displayed error message, you must resolve the signal problem in order to permanently
eliminate the message.
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 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 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 LED status display window next to the
built-in keypad. A system malfunction can be cleared with
Exit
Exit
from
presentation level, but may indicate 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 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 potentially serious problem that
