NOTE: Error messages also always appear at the rear LCD next to the keypad.
Invalid User Entry
'
Any keypad entry not recognized by the projector will trigger an on-screen error
message describing the problem. For example, if you specify a channel number that
has not been defined, the message "Invalid Channel will appear. Or if you try to enter
the wrong password, you'll see "Invalid Password". Press
message and eliminate the message box.
NOTE: Displaying of "Invalid User Entry" messages cannot be disabled, even if
Display Error Messages has been set to "Off".
'
Input signal errors messages appear when you are in presentation level (i.e., when
there are no menus present) and have selected an input on which the projector detects
a problem. While menus remain operational and pressing any key will temporarily
remove the message from the screen, you must resolve the signal problem in order to
permanently eliminate the message.
NOTE: Input signal messages appear on-screen only if Display Error Messages has
been set to "Screen" or "All".
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.
'
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). A system warning message replaces any input signal
Enter or Exit to confirm the
