Roadie 25K User's Manual
Note that text-based status/error messages also appear in the LCD Status Display
window above the keypad at the rear of the projector. They are accompanied by their
corresponding 2-digit error code next to the
keypad, legible at a greater distance. Normal
operation is indicated by the "00"status code.

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
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 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 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 "Status" LED and a related text
message in the LCD Status Display window. 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".
